[PATCH net-next v4 04/15] net: dsa: vsc73xx: Add define for max num of ports
Posted by Pawel Dembicki 1 year, 12 months ago
This patch introduces a new define: VSC73XX_MAX_NUM_PORTS, which can be
used in the future instead of a hardcoded value.

Currently, the only hardcoded value is vsc->ds->num_ports. It is being
replaced with the new define.
