Same problem for any NAPI context Tx completing driver that claims
netpoll support. For instance:
drivers/net/ethernet/emulex/benet
drivers/net/ethernet/intel/i40e
drivers/net/ethernet/intel/igb
drivers/net/ethernet/intel/ixgbe
drivers/net/ethernet/marvell/sky2.c
drivers/net/ethernet/neterion/vxge ?

Similar problem for the drivers below. They update Tx stats in start_xmit
and use u64_.*_bh:
drivers/net/ethernet/tile/tilepro.c
drivers/net/team/team.c
drivers/net/virtio_net.c
