net/mlx5: Enable 4 ports multiport E-switch
[ Upstream commit e738e355045237ee8802cb2b31a8ed6f4b7ac534 ]
enable_mpesw() assumed only 2 ports are available, fix this by removing
that assumption and looping through the existing lag ports to enable multi-port
E-switch for cards with more than 2 ports.
