Subject: [PATCH net-next v2 2/3] net: phy: marvell-88x2222: move read_status after config_aneg
Date: Tue, 13 Apr 2021 23:54:51 +0300 [thread overview]
Message-ID: <088186566508e52bf3c4e8fea568eebea023fd3a.1618347034.git.i.bornyakov@metrotek.ru> (raw)
In-Reply-To: <cover.1618347034.git.i.bornyakov@metrotek.ru>
No functional changes, just move read link status routines below
autonegotiation configuration to make future functional changes more
distinct.
