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.
