Subject: [PATCH net-next 3/6] net: ethernet: ti: am65-cpsw-nuss: fix ports mac sl initialization
Date: Fri, 26 Jun 2020 21:17:06 +0300	[thread overview]
Message-ID: <20200626181709.22635-4-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20200626181709.22635-1-grygorii.strashko@ti.com>

The MAC SL has to be initialized for each port otherwise
am65_cpsw_nuss_slave_disable_unused() will crash for disabled ports.

Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com>

Not critical as current driver supports one port only.
