net/mlx5e: Update MPWQE stride size when modifying CQE compress state
When the admin enables/disables cqe compression, updating mpwqe stride size is required: CQE compress ON ==> stride size = 256B CQE compress OFF ==> stride size = 64B This is already done on driver load via mlx5e_set_rq_type_params, all we need is just to call it on arbitrary admin changes of cqe compression state via priv flags or when changing timestamping state (as it is mutually exclusive with cqe compression). This bug introduces no functional damage, it only makes cqe compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Tested: ethtool --set-priv-flags ethxx rx_cqe_compress on pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 7219ab34f184 ("net/mlx5e: CQE compression") Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: David S.
