[net-next,mlxsw,1/6] mlxsw: spectrum_router: Propagate extack to .fid_get()

Commit Message

Petr Machata June 5, 2018, 1:37 p.m. UTC

In the follow-up patch, mlxsw_sp_rif_vlan_fid_get() will be changed in a
way that could fail. Give that function a possibility to explain the
failure through extack.
