From 3f47f867814cdb08cd43d4b82f95bfde4a9ae579 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Wed, 27 Jan 2016 15:20:25 +0100 Subject: [PATCH] mlxsw: spectrum: Compare local ports instead of pointers When dumping the FDB we can't compare the actual pointers of the ports structs, as it's possible the struct represents a vPort instead of the underlying physical port. Solve this by comparing the local port number instead, as it's shared between the physical ports and all the vPorts on top of him.
