From: Felix Fietkau Date: Sun, 3 Jan 2016 23:13:16 +0000 (+0000) Subject: kernel: add at803x fix for sgmii mode X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e14d2aee0ab91c43d0bb14baf84cc9b997185870;p=openwrt%2Fstaging%2Fyousong.git kernel: add at803x fix for sgmii mode Some (possibly broken) bootloaders incorreclty initialize at8033 phy. This patch enables sgmii autonegotiation mode.
