Merge tag 'v5.11' into rdma.git for-next
Linux 5.11 Merged to resolve conflicts with RDMA rc commits - drivers/infiniband/sw/rxe/rxe_net.c The final logic is to call rxe_get_dev_from_net() again with the master netdev if the packet was rx'd on a vlan. To keep the elimination of the local variables requires a trivial edit to the code in -rc Link: https://lore.kernel.org/r/20210210131542.215ea67c@canb.auug.org.au Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
