Subject: [PATCH] net: cpsw: fix ethernet bringup in case of a fixed-link phy
Date: Tue, 31 Aug 2021 12:57:01 +0000	[thread overview]
Message-ID: <1630414594-10601-1-git-send-email-oleg.karfich@wago.com> (raw)

In case of a fixed-link phy the cpsw_adjust_link() function is
called directly in phy_device_attach() and configures the MACCONTROL
register. Right after this configuration cpsw_init() is called and
resets the MACCONTROL register.
Fix this by initializing the slave before connecting the phy device in
cpsw_open().
