In commit 5b6490def9168af6a ("3c59x: Use setup_timer()") Amitoj
removed add_timer which sets up the epires timer. In this patch
the behavior is restore but it uses mod_timer which is a bit more
compact.

====================
1GbE Intel Wired LAN Driver Updates 2016-02-24
This series contains updates to e1000e, igb and igbvf.
Raanan provides updates for e1000e, first increases the ULP timer since it
now takes longer for the ULP exit to complete on Skylake. Fixes the
configuration of the internal hardware PHY clock gating mechanism, which was
causing packet loss due to mis configuring. Fixed additional ULP
configuration settings which were not being properly cleared after cable
connect in V-Pro capable systems. Added support for more i219 devices.
Takuma Ueba provides a fix for I210 where IPv6 autoconf test sometimes
fails due to DAD NS for link-local is not transmitted. To avoid this
issue, we need to wait until 1000BASE-T status register "Remote receiver
status OK".
Todd provides a patch to override EEPROM WoL settings for specific OEM
devices. Then renamed igb defines to be more generic, since the define
E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part.
Roland Hii fixes an issue where only the half cycle time of less than or
equal to 70 millisecond uses the I210 clock output function. His patch
adds additional conditions when half cycle time is equal to 125 or 250 or
500 millisecond to use the clock output function.
Alex Duyck adds support for generic transmit checksums for igb and igbvf.
Jon Maxwell fixes an issues where customer applications are registering
and un-registering multicast addresses every few seconds which is leading
to many "Link is up" messages in the logs as a result of the
netif_carrier_off(netdev) in igbvf_msix_other(). So remove the
link is up message when registering multicast addresses.
Corinna Vinschen provides a fix for when switching off VLAN offloading on
i350, the VLAN interface becomes unusable.
Stefan Assmann updates the driver to use ndo_stop() instead of
dev_close() when running ethtool offline self test. Since dev_close()
causes IFF_UP to be cleared which will remove the interfaces routes
and some addresses.
v2: Dropped patches 6-10 in the original series. Patch 6-7 added support
for character device for AVB and based on community feedback, we do not
want to do this. Patches 8-10 provided fixes to the problematic code
added in patches 6 & 7. So all of them must go!

When CONFIG_GENEVE is built as a loadable module, and bnx2x is built-in,
we get this link error:
drivers/net/built-in.o: In function `bnx2x_open':
:(.text+0x33322): undefined reference to `geneve_get_rx_port'
drivers/net/built-in.o: In function `bnx2x_sp_rtnl_task':
:(.text+0x3e632): undefined reference to `geneve_get_rx_port'
This avoids the problem by adding a separate Kconfig symbol named
CONFIG_BNX2X_GENEVE that is only enabled when the code is
reachable from the driver.
This is the same trick that BNX2X does for VXLAN support, and
is similar to how I40E handles both.

Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

Problem: When switching off VLAN offloading on an i350, the VLAN
interface gets unusable. For testing, set up a VLAN on an i350
and some remote machine, e.g.:
$ ip link add link eth0 name eth0.42 type vlan id 42
$ ip addr add 192.168.42.1/24 dev eth0.42
$ ip link set dev eth0.42 up
Offloading is switched on by default:
$ ethtool -k eth0 | grep vlan-offload
rx-vlan-offload: on
tx-vlan-offload: on
$ ping -c 3 -I eth0.42 192.168.42.2
[...works as usual...]
Now switch off VLAN offloading and try again:
$ ethtool -K eth0 rxvlan off
Actual changes:
rx-vlan-offload: off
tx-vlan-offload: off [requested on]
$ ping -c 3 -I eth0.42 192.168.42.2
PING 192.168.42.2 (192.168.42.2) from 192.168.42.1 eth0.42: 56(84) bytes of da
ta.
--- 192.168.42.2 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 1999ms
I can only reproduce it on an i350, the above works fine on a 82580.
While inspecting the igb source, I came across the code in igb_set_vmolr
which sets the E1000_VMOLR_STRVLAN/E1000_DVMOLR_STRVLAN flags once and
for all, and in all of the igb code there's no other place where the
STRVLAN is set or cleared. Thus, VLAN stripping is enabled in igb
unconditionally, independently of the offloading setting.
I compared that to the latest Intel igb-5.3.3.5 driver from
http://sourceforge.net/projects/e1000/ which in fact sets and clears the
STRVLAN flag independently from igb_set_vmolr in its own function
igb_set_vf_vlan_strip, depending on the vlan settings.
So I included the STRVLAN handling from the igb-5.3.3.5 driver into our
current igb driver and tested the above scenario again. This time ping
still works after switching off VLAN offloading.
Tested on i350, with and without addtional VFs, as well as on 82580
successfully.

A similar issue was addressed a few years ago in the following thread:
http://www.spinics.net/lists/netdev/msg245877.html
At that time there were concerns that removing this statement may cause other
side effects. However the submitter addressed those concerns. But the dialogue
went cold. We have a new case where a customers application is registering and
un-registering multicast addresses every few seconds. This is leading to many
"Link is Up" messages in the logs as a result of the
"netif_carrier_off(netdev)" statement called by igbvf_msix_other(). Also on
some kernels it is interfering with the bonding driver causing it to failover
and subsequently affecting connectivity.
The Sourgeforge driver does not make this call and is therefore not affected.
If there were any side effects I would expect that driver to also be affected.
I have tested re-loading the igbvf driver and downing the adapter with the PF
entity on the host where the VM has this patch. When I bring it back up again
connectivity is restored as expected. Therefore I request that this patch gets
submitted.

This patch adds support for generic Tx checksums to the igbvf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

In general case the maximum supported half cycle time of the synchronized
output clock is 70msec. Slower half cycle time than 70msec can be
programmed also as long as the output clock is synchronized to whole
seconds, useful specifically for generating a 1Hz clock.
Permitted values for the clock half cycle time are: 125,000,000 decimal,
250,000,000 decimal and 500,000,000 decimal (equals to 125msec, 250msec
and 500msec respectively).
Before this patch, only the half cycle time of less than or equal to 70msec
uses the I210 clock output function. This patch adds additional conditions
when half cycle time is equal to 125msec or 250msec or 500msec to use
clock output function.
Under other conditions, interrupt driven target time output events method
is still used to generate the desired clock output.
