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
