New scheme calls for 3rd party VPD at offset 0x0 and Chelsio VPD at offset
0x400 of the function. If no 3rd party VPD is present, then a copy of
Chelsio's VPD will be at offset 0x0 to keep in line with PCI spec which
requires the VPD to be present at offset 0x0.

Commit f4a46d1f46a8fece34edd2023e054072b02e110d introduced a bug where
the ifconfig stats would remain 0 for phylib devices. This is due to
tp->link_up flag never becoming true causing tg3_periodic_fetch_stats()
to return.
The link_up flag was being updated in tg3_test_and_report_link_chg()
after setting up the phy. This function however, is not called for
phylib devices since the driver does not do the phy setup.
This patch moves the link_up flag update into the common
tg3_link_report() function that gets called for phylib devices as well
for non phylib devices when the link state changes.
To avoid updating link_up twice, we replace tg3_carrier_...() calls that
are followed by tg3_link_report(), with netif_carrier_...(). We can then
remove the unused tg3_carrier_on() function.

When a KR2 device is connected to a KR link-partner, sometimes it requires
disabling KR2 for the link to come up. To get a KR2 link up later, in case no
base pages are seen, the KR2 is restored. The problem was that some link
partners cleared their advertised BP/NP after around two seconds, causing the
driver to disable/enable KR2 link all the time.
The fix was to wait at least 5 seconds before checking KR2 recovery.

Commit 37706996 "mlx4_en: fix allocation of CPU affinity reverse-map" fixed
a bug when mlx4_dev->caps.comp_pool is larger from the device rx rings, but
introduced a regression.
When the mlx4_core is activating its "legacy mode" (e.g when running in SRIOV
mode) w.r.t to EQs/IRQs usage, comp_pool becomes zero and we're crashing on
divide by zero alloc_cpu_rmap.
Fix that by enabling RFS only when running in non-legacy mode.

The set_param_l function assumes casting a u64 pointer to a u32 pointer
allows to access the lower 32bits, but it results in writing the upper
32 bits on big endian systems.
The fixed function reads the upper 32 bits of the 64 argument, and or's
them with the 32 bits of the 32-bit value passed to the function.
Since this is now a "read-modify-write" operation, we got many
"unintialized variable" warnings which needed to be fixed as well.

This patch removes redundant actions from driver and fixes its interaction
with actions in pci-bus runtime power management code.
It removes pci_save_state() from __e1000_shutdown() for normal adapters,
PCI bus callbacks pci_pm_*() will do all this for us. Now __e1000_shutdown()
switches to D3-state only quad-port adapters, because they needs quirk for
clearing false-positive error from downsteam pci-e port.
pci_save_state() now called after clearing bus-master bit, thus __e1000_resume()
and e1000_io_slot_reset() must set it back after restoring configuration space.
This patch set get_link_status before calling pm_runtime_put() in e1000_open()
to allow e1000_idle() get real link status and schedule first runtime suspend.
This patch also enables wakeup for device if management mode is enabled
(like for WoL) as result pci_prepare_to_sleep() would setup wakeup without
special actions like custom 'enable_wakeup' sign.

This time just passing along a big batch of fixes from Johannes...
For the mac80211 bits:
"Here I have fixes from Ben Greear for stray work items when deleting
interfaces, another idle handling fix from Felix, a fix from Marco ro a
mesh PS buffering crash and I have a fix for the VHT MCS calculation in
association request frames and more nl80211 feature advertising removal
as well as a workaround to increase the dump size if the SKB overhead is
too large. For 3.10 I already have a complete fix queued, but that also
requires (simple) userspace changes."
And for the iwlwifi bits:
"The patches from Dor fix a bunch of calibration issues in the new MVM
driver, and Emmanuel has a number of fixes there as well. Also, we
decided to disable 8k A-MSDU by default, so that's in there. My own
patches are addressing an issue we found with the new devices but that
seems to also exist on older ones, the DMA writeback the devices do can
be delayed and cause issues. The fix is unfortunately relatively large
and depends on two other changes (to not be hugely conflicting), but I
think it's still worth it at this point."
As Johannes says, it is a bit large. But I hope it is still early
enough in the cycle to make that worthwhile.

RX DMA buffers start at an offset of EFX_PAGE_IP_ALIGN bytes from the
start of a cache line. This offset obviously needs to be included in
the virtual address, but this was missed in commit b590ace09d51

EFX_PAGE_IP_ALIGN is equal to 0 on both x86 and powerpc.

efx_device_detach_sync() locks all TX queues before marking the device
detached and thus disabling further TX scheduling. But it can still
be interrupted by TX completions which then result in TX scheduling in
soft interrupt context. This will deadlock when it tries to acquire
a TX queue lock that efx_device_detach_sync() already acquired.
To avoid deadlock, we must use netif_tx_{,un}lock_bh().

While PCI card faces EEH errors, reset (usually hot reset) is
expected to recover from the EEH errors. After EEH core finishes
the reset, the driver callback (be_eeh_reset) is called and wait
the firmware to complete POST successfully. The original code would
return with error once detecting failure during POST stage. That
seems not enough.
The patch forces the driver (be_eeh_reset) to wait the firmware
completes POST until timeout, instead of returning error upon
detection POST failure immediately. Also, it would improve the
reliability of the EEH funtionality of the driver.

We should reset nf settings bond to the skb as ipip/ipgre do.
If not, the conntrack/nat info bond to the origin packet may continually
redirect the packet to vxlan interface causing a routing loop.
this is the scenario:
VETP VXLAN Gateway
/----\ /---------------\

| vx+--+vx --NAT-> eth0+--> Internet
| | | |
\----/ \---------------/
when there are any packet coming from internet to the vetp, there will be lots
of garbage packets coming out the gateway's vxlan interface, but none actually
sent to the physical interface, because they are redirected back to the vxlan
interface in the postrouting chain of NAT rule, and dmesg complains:

Jeff Kirsher says:
===================
This series contains fixes to e1000e and igb.
The e1000e fix resolves an issue at 1000Mbps link speed, where one of the
MAC's internal clocks can be stopped for up to 4us when entering K1 (a
power mode of the MAC-PHY interconnect). If the MAC is waiting for
completion indications for 2 DMA write requests into Host memory
(e.g. descriptor writeback or Rx packet writing) and the
indications occur while the clock is stopped, both indications will be
missed by the MAC causing the MAC to wait for the completion indications
and be unable to generate further DMA write requests. This results in an
apparent hardware hang. The patch works-around the issue by disabling
the de-assertion of the clock request when 1000Mbps link is acquired (K1
must be disabled while doing this).
The igb fix to drop BUILD_BUG_ON check from igb_build_rx_buffer resolves
a build error on s390 devices. The igb driver was throwing a build error
due to the fact that a frame built using build_skb would be larger than 2K.
Since this is not likely to change at any point in the future we are better
off just dropping the check since we already had a check in
igb_set_rx_buffer_len that will just disable the usage of build_skb anyway.
The igb fix for i210 link setup changes the setup copper link function
to use a switch statement, so that the appropriate setup link function
is called for the given PHY types.
Lastly, the igb fix for a lockdep issue in igb_get_i2c_client resolves
the issue by re-factoring the initialization and usage of the i2c_client.

At 1000Mbps link speed, one of the MAC's internal clocks can be stopped for
up to 4us when entering K1 (a power mode of the MAC-PHY interconnect). If
the MAC is waiting for completion indications for 2 DMA write requests into
Host memory (e.g. descriptor writeback or Rx packet writing) and the
indications occur while the clock is stopped, both indications will be
missed by the MAC causing the MAC to wait for the completion indications
and be unable to generate further DMA write requests. This results in an
apparent hardware hang.
Work-around the issue by disabling the de-assertion of the clock request
when 1000Mbps link is acquired (K1 must be disabled while doing this).

stat_xmit just update fep->cur_tx
fec_enet_tx just update fep->dirty_tx
Reserve a empty bdb to check full or empty
cur_tx == dirty_tx means full
cur_tx == dirty_tx +1 means empty
So needn't is_full variable.

This flow happens when we get a failed single Tx response
on an AMPDU queue. In this case, the frame won't be sent
any more. So we need to move the window on the recipient
side. This is done by a BAR.
Now if we are in the following case: 10, 12 and 13 are ACKed
and 11 isn't.
10 11 12 13.
V X V V
Then, 11 will be sent 16 times as an MPDU (as oppsed to
A-MPDU). If this failed, we are entering the flow described
above. So we need to send a BAR with ssn = 12.
But in this case, the scheduler will tell us to free frames
up to 13 (included).
So, it is perfectly possible to get a failed single Tx
response on an AMPDU queue that makes the scheduler's ssn
jump by more than 1 single packet.

Since the device is being restarted, all the Rx / Tx Block
Ack sessions are been wiped out by the driver. So ignore
the requests from mac80211 that stops Tx agg while
reconfiguring the device.
Note that stopping a non-existing Rx BA session is harmless,
so just honor mac80211's request.

This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and resume functions.
Serveral variables allocted dynamically were removed and replaced by stack variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.
This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

o The Qualcomm Atheros platform is extended by support for the new
QCA955X SoC series as well as a bunch of patches that get the code
ready for OF support.
o Lantiq and BCM47XX platform have a few improvements and bug fixes.
o MIPS has sent a few patches that get the kernel ready for the
upcoming microMIPS support.
o The rest of the series is made up of small bug fixes and cleanups
that relate to various parts of the MIPS code. The biggy in there is
a whitespace cleanup. After I was sent another set of whitespace
cleanup patches I decided it was the time to clean the whitespace
"issues" for once and and that touches many files below arch/mips/.
Fix up silly conflicts, mostly due to whitespace cleanups.
