Support for phys switch id ndo added for representors and if we do not have representors there is no need to support it. Since each port return different switch id supporting this block support for creating bond over PFs and attaching to bridge in legacy mode.

This bug doesn't exist upstream as the code got refactored and the netdev api is totally different.

Fixes: cb67b832921c ("net/mlx5e: Introduce SRIOV VF representors") Signed-off-by: Roi Dayan roid@mellanox.com Signed-off-by: Saeed Mahameed saeedm@mellanox.com --- Hi Greg,

Sorry for submitting a non upstream patch, but this bug is bothering some users on 4.19-stable kernels and it doesn't exist upstream, so i hope you are ok with backporting this one liner patch.

Thanks !!
