====================
nfp: fix retcode and disable netpoll on representors
This series avoids a potential crash on nfp representor devices
when netpoll is in use. If transmitting the frame through underlying
vNIC fails we'd return an error code (by passing on error code from
__dev_queue_xmit()) and cause double free in netpoll code.
Fix the error code and disable netpoll on reprs altogether.
IRQ-safety of locking the queues and calling __dev_queue_xmit()
is questionable.
Big thanks to John Hurley for debugging and narrowing down
the trace log after I gave up! :)
