Keep the descriptor ring size in the actual ring structs instead of in
the adapter struct. This enables us to use common tx and rx code with
the i40e PF driver.

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.

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.

Remove a bunch of unused structure members that are just wasting
space. Remove a completely unused info structure definition as well.

This patch contains the main driver header files, containing structures
and data types specific to the linux driver.
i40e_osdep.h contains some code that helps us adapt our OS agnostic code
to Linux.
