From: Mathias Kresin Date: Mon, 2 Jul 2018 20:09:04 +0000 (+0200) Subject: kernel: fix AT8032 PHY phy id mask X-Git-Tag: v19.07.0-rc1~3267 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=eccde89aa4764fd16b490e96e5dbbdb51cb0051b;p=openwrt%2Fstaging%2Fpepe2k.git kernel: fix AT8032 PHY phy id mask Don't mask bit 4 of the AT8022 phy id. If bit 4 of the AT8022 phy id (0x004dd023) is masked, it will match the phy id of the AR8327 switch (0x004dd033) as well. It results in applied at803x driver settings/callbacks, which will at least limit the AR8327 phys to 100MBit operation instead of the possible 1000MBit.
