This change makes it so that only the first fragment in a series of fragments
will have the L4 header pulled. Previously we were always pulling the L4
header as well and in the case of UDP this can harm performance since only the
first fragment will have the header, the rest just contain data which should
be left in the paged portion of the packet.

Historically, we've been using the APME bit to determine whether a device
supports wake on a given port or not. However, this bit specifies the
default wake setting, rather than the wake support. Change the behavior so
that we use a flag to keep the capabilities separate from the enablement
while meeting customer requirements.

Update the filters to be more consistent with what the driver wants to do.
For example, for devices that timestamp all packets, report that the filter
is set for timestamping all packets.

There was a bitwise operation error in the fdb_add block
that was only allowing FDB types that were not permanent.
This was the opposite of the intent because the hardware
never ages out address these are the _only_ type of addrs
that should be allowed.
This was missed because until recently iproute2 did not
set any bit for this by default. And our test code to
manage FDB entries on embedded devices similarly did not
set these bits.
I am going to chalk this up as a bug and fix it now.

This patch enables ethtool to correctly identify flow control (pause
frame) auto negotiation, as well as disallow enabling it when it is not
supported. The ixgbe_device_supports_autoneg_fc function is exported and
used for this purpose.
There is also one minor cleanup of the device_supports_autoneg_fc by
removing an unnecessary return statement.

This patch removes the queuing that was previously done for L4 packets
as it is not needed. The filter does not provide functionality, and it
is possible that queue setup here could trample settings done else-where
in the driver. (for example it may use a queue which isn't setup.)
Setting of the queue is not required for hardware timestamping and could
have inadverdent side effects.

This patch removes a magic number that was used for the ETQF used for
filtering L2 ptp packets and replaces it with the supplied define that
previously existed. The intent is to clarify that this filter is already
set aside for L2 1588 work.

This patch provides extensions to VXLAN for supporting Distributed
Overlay Virtual Ethernet (DOVE) networks. The patch includes:
+ a dove flag per VXLAN device to enable DOVE extensions
+ ARP reduction, whereby a bridge-connected VXLAN tunnel endpoint
answers ARP requests from the local bridge on behalf of
remote DOVE clients
+ route short-circuiting (aka L3 switching). Known destination IP
addresses use the corresponding destination MAC address for
switching rather than going to a (possibly remote) router first.
+ netlink notification messages for forwarding table and L3 switching
misses
Changes since v2
- combined bools into "u32 flags"
- replaced loop with !is_zero_ether_addr()

If ndo_validate_addr is set to the generic eth_validate_addr
function there is no point in calling is_valid_ether_addr
from driver ndo_open if ndo_open is not used elsewhere in
the driver.
With this change is_valid_ether_addr will be called from the
generic eth_validate_addr function. So there should be no change
in the actual behavior.

Move to circular buffers management macro and correct an error
with circular buffer initial condition.
Without this patch, the macb_tx_ring_avail() function was
not reporting the proper ring availability at startup:
macb macb: eth0: BUG! Tx Ring full when queue awake!
macb macb: eth0: tx_head = 0, tx_tail = 0
And hanginig forever...
I remove the macb_tx_ring_avail() function and use the
proven macros from circ_buf.h. CIRC_CNT() is used in the
"consumer" part of the driver: macb_tx_interrupt() to match
advice from Documentation/circular-buffers.txt.

It is unnecessary to disable preemption explicitly while calling
copy_highpage(). Because copy_highpage() will do it again through
kmap_atomic/kunmap_atomic.

The TTM page can be allocated from high memory. In such case it is
wrong to use the page_address(page) as the virtual address for the high memory
page.

copy_to_user() returns the number of bytes remaining to be copied, but
we want to return a negative error code here. I fixed a couple of these
last year, but I missed this one.

====================
this pull request is for net-next, for the v3.8 release cycle. Muhammad
Ghias added support another board to the plx_pci sja1000 driver.
Matthias Fuchs improved the esd_usb2 driver with listen-only mode and
CAN-USB/Micro support. Andreas Larsson contributed a driver for the
GRHCAN CAN IP-Core

This patch re-enables Energy Detect Power Down (EDPD) mode for the
LAN8710/LAN8720. EDPD mode was disabled in a previous commit,
(b629820d18fa65cc598390e4b9712fd5f83ee693), because it was causing the
PHY to not be able to detect a link when cold started without a cable
connected.
The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of
each other in order to set the ENERGYON bit and exit EDPD mode. If a
link partner does send the pulses within this interval, the PHY will
remained powered down.
This workaround will manually toggle the PHY on/off upon calls to
read_status in order to generate link test pulses if the link is down.
If a link partner is present, it will respond to the pulses, which will
cause the ENERGYON bit to be set and will cause the EDPD mode to be
exited.
