On some kernels (Debian 6.6, 6.9 and 6.10 tested),
there is a missing option for "TC recirculation"
that prevents MLX5 driver to include CONFIG_MLX5_CLS_ACT
in the compilation, thus preventing PF1
from properly working in multiport-eswitch mode.

Fixes: 11c73de9ef63 ("net/mlx5: probe multi-port E-Switch device")

v2:
- Added additional MLX5 kernel option
- Fixed patch formatting
- Added "Fixes" tag
