Merge branch 'nfp-fixes'
Jakub Kicinski says: ==================== nfp: fix SR-IOV deadlock and representor bugs This series tackles the bug I've already tried to fix in commit 6d48ceb27af1 ("nfp: allocate a private workqueue for driver work"). I created a separate workqueue to avoid possible deadlock, and the lockdep error disappeared, coincidentally. The way workqueues are operating, separate workqueue doesn't necessarily mean separate thread of execution. Luckily we can safely forego the lock. Second fix changes the order in which vNIC netdevs and representors are created/destroyed. The fix is kept small and should be sufficient for net because of how flower uses representors, a more thorough fix will be targeted at net-next. Third fix avoids leaking mapped frame buffers if FW sent a frame with unknown portid. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
