Subject: [PATCH net v1] net: dsa: ksz8795: use correct number of physical ports

From: Sven Van Asbroeck <thesven73@...il.com>

The ksz8795 has five physical ports, but the driver assumes
it has only four. This prevents the driver from working correctly.

Fix by indicating the correct number of physical ports.
