Merge branch 'nfp-fix-retcode-and-disable-netpoll-on-representors'
Jakub Kicinski says: ==================== 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! :) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
