Looks really nice, series applied, thanks!

Jiri, just FYI, I bungled up merging this.  And I am trying to fix
that up.

I forgot to include patch #14, but I'll apply that now in the
mainline.

I get a warning, in mlxsw_sp_nexthop_group_create() because the
compiler thinks that 'nh' can be use uninitialized.  And I think
the compiler is pointing out something legitimate.

This cleanup loop in err_nexthop_group_insert and err_nexthop_init
needs to take the 'nh' from &nh_grp->nexthops[i] instead of using
whatever is left in 'nh' for all mlxsw_sp_nexthop_fini() calls.

So I'm going to augment the commit of patch #14 to make it go:

@@ -1667,8 +1667,10 @@ mlxsw_sp_nexthop_group_create(struct mlxsw_sp *mlxsw_sp, struct fib_info *fi)
