hmmm, i was too optimistic, patches got blocked by CI, apparently some
changes in mlx5 eswitch API are causing the following failure, most
likely due to the introduction of eswitch_chains API.

05:57:47 make -s -j 96 CC=/usr/llvm/bin/clang
drivers/net/ethernet/mellanox/mlx5/core/
05:58:14 error: drivers/net/ethernet/mellanox/mlx5/core/en_rep.c:752:8:
error: implicit declaration of function 'mlx5_eswitch_prios_supported'

note: did you mean 'mlx5_esw_chains_prios_supported'?
