From: Rafał Miłecki Date: Fri, 13 Oct 2017 12:06:18 +0000 (+0200) Subject: kernel: add fix for bgmac with B50212E B1 PHY X-Git-Tag: v17.01.4~17 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8ad1b09c6dcff814eb04084ef349f975025b7dc1;p=oweals%2Fopenwrt.git kernel: add fix for bgmac with B50212E B1 PHY This PHY requires some extra programming to work reliably with all devices. Backport upstream fix for it.
