2 Subject: [PATCH] ath79: allow to override AR8033 SGMII aneg status
4 In order to make the QCA955x SGMII workaround work, the unsuccessful
5 SGMII autonegotiation on the AR8033 should not block the PHY
8 Otherwise, the ag71xx driver never becomes aware of the copper-side
9 link-establishment and the workaround is never executed.
