Mitch Williams dbb01c8aa0 i40evf: fix multiple crashes on remove
Depending upon the state of the driver, there are several potential
pitfalls on remove. Kill the watchdog task so rmmod doesn't hang.
Check the adapter->msix_entries field, not the num_msix_vectors field,
which is never cleared.

We remove all the MAC filters, so remove the VLAN filters, too.

Mitch Williams 625777e386 i40evf: request reset on tx hang
If the kernel watchdog bites us, ask the PF to reset us and attempt to
reinit the driver.

Mitch Williams ef8693eb90 i40evf: refactor reset handling
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.

Also update copyrights.

Mitch Williams e1dfee8e64 i40evf: don't store unnecessary array of strings
Since we store the traffic vector names in the queue vector struct, we
don't need to maintain an array of strings for these names in the
adapter structure. Replace this array with a single string and use it
when allocating the misc irq vector.

Also update copyrights.
