Intel Wired LAN Driver Updates
This series contains updates to i40e and i40evf, primarily reset
handling / refactoring along with a fair amount of minor cleanup.
Jesse fixes some spelling, bumps the version and other trivial fixes.
Akeem sets a bit that is needed before shutdown in the case of
tx_timeout recovery failure. Mitch refactors reset handling along
with a whole bunch of clean up.

Respond better to a VF reset event. When a reset is signaled by the
PF, or detected by the watchdog task, prevent the watchdog from
processing admin queue requests, and schedule the reset task.
In the reset task, wait first for the reset to start, then for it to
complete, then reinit the driver.
If the reset never appears to complete after a long, long time (>10
seconds is possible depending on what's going on with the PF driver),
then set a flag to indicate that PF communications have failed.
If this flag is set, check for the reset to complete in the watchdog,
and attempt to do a full reinitialization of the driver from scratch.
With these changes the VF driver correctly handles a PF reset event
while running on bare metal, or in a VM.

As pointed out by Dan Carpenter (from Oracle), the flags variable is
declared as a 64-bit long but all of the flags are defined as u32,
which may lead to unintended consequences. Fix this by declaring flags
as u32 (since we don't need any more than about a dozen flags right
now), and remove the volatile qualifier, since it's unnecessary and
just makes checkpatch cry.

2. FCoE traffic fails to run when running in switch-independent multi-function

3. While two ports are running FCoE with at least one of them has a function
number (>1) on the same engine in a 4-port device a zeroed CQE is given,
causing FCoE traffic to stop.

phy_print_status() currently uses dev_name(&phydev->dev) which will
usually result in printing something along those lines for Device Tree
aware drivers:
libphy: f0b60000.etherne:0a - Link is Down
libphy: f0ba0000.etherne:00 - Link is Up - 1000/Full
This is not terribly useful for network administrators or users since we
expect a network interface name to be able to correlate link events with
interfaces. Update phy_print_status() to use netdev_info() with
phydev->attached_dev which is the backing network device for our PHY
device. The leading dash is removed since netdev_info() prefixes the
messages with "<interface>: " already.
