Subject: net/mlx5e: IPoIB, Initialize max_opened_tc in mlx5i_init flow
Patch-mainline: v4.20-rc1
Git-commit: 6dae6f06f0fc0096213dde2203c335938d3bde99
References: bsc#1103990 FATE#326006

Enhanced ipoib does not initialize max_opened_tc causing wrong ethtool
statistics. As mlx5e_grp_sw_update_stats relies on this variable, without
this change, the TX statistics will not be updated.

Fixes: 05909babce53 ("net/mlx5e: Avoid reset netdev stats on configuration changes")
