From: David Bauer Date: Fri, 4 Jun 2021 13:12:14 +0000 (+0200) Subject: generic: backport at803x fixes X-Git-Tag: mikrotik~1906 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=15167671b0d7cf0c95568dd6f9620db082df5d96;p=openwrt%2Fstaging%2Fchunkeey.git generic: backport at803x fixes As patches for the AR8031/AR8033 copper page selection were merged upstream, we can backport these patches. This also fixes a PHY capabilities detection issue on the Ubiquiti ER-X-SFP.
