[PATCH net-next 3/6] net: ethernet: ti: am65-cpsw-nuss: fix ports mac sl initialization
From: Grygorii Strashko
Date: Fri Jun 26 2020 - 14:17:33 EST
The MAC SL has to be initialized for each port otherwise
am65_cpsw_nuss_slave_disable_unused() will crash for disabled ports.

Not critical as current driver supports one port only.
