[dpdk-dev] [PATCH v1] net/mlx5: fix flow type for allmulti rules

[Raslan Darawsheh <rasland@mellanox.com>]

Chnaged ibv_flow_attr type for allmulti rule to IBV_FLOW_ATTR_MC_DEFAULT
instead of IBV_FLOW_ATTR_NORMAL, in case allmulti was enabled.

Fixes: 272733b5 ("net/mlx5: use flow to enable unicast traffic")
