Subject: [PATCH net-next 1/4] net/mlx5e: IPoIB, Initialize max_opened_tc in mlx5i_init flow

From: Feras Daoud <ferasda@...lanox.com>

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")
