Are you asking for the patch for this feature to include the queue
stop/start instead of this? I just checked linux-pci and it does have
bnxt_queue_stop/bnxt_queue_start.

The queue reset _has_ to work. We will ensure that it does and fix any
problems found. Note that these have been under test already internally
and fixes are/will be posted to the list as they are made. Holding this
patch because an API that it uses might not work seems odd.
