Subject: [PATCH 0/5 net-next] ibmvnic: Miscellaneous driver fixes and enhancements

There is not a general theme to this patch set other than that it
fixes a few issues with the ibmvnic driver. I will just give a quick
summary of what each patch does here.

"ibmvnic: Fix TX descriptor tracking again" resolves a race condition
introduced in an earlier fix to track outstanding transmit descriptors.
This condition can throw off the tracking counter to the point that
a transmit queue will halt forever.

"ibmvnic: Allocate statistics buffers during probe" allocates queue
statistics buffers on device probe to avoid a crash when accessing
statistics of an unopened interface.

"ibmvnic: Harden TX/RX pool cleaning" includes additional checks to
avoid a bad access when cleaning RX and TX buffer pools during a device
reset.

"ibmvnic: Report queue stops and restarts as debug output" changes TX
queue state notifications from informational to debug messages. This
information is not necessarily useful to a user and under load can result
in a lot of log output.

"ibmvnic: Do not attempt to login if RX or TX queues are not allocated"
checks that device queues have been allocated successfully before
attempting device login. This resolves a panic that could occur if a
user attempted to configure a device after a failed reset.

Thanks for your attention.
