Subject: [PATCH net 2/5] selftests: mlxsw: Add test cases for local table route replacement
From: Ido Schimmel <idosch@...lanox.com>
Test that routes in the main table do not replace identical routes in
the local table and that routes in the local table do replace identical
routes in the main table.
