Subject: realtek: enable MDI swapping for RTL8226 where needed
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b943db9cb2a2780e9244d10582ee873e6c01ee7f;p=thirdparty%2Fopenwrt.git

realtek: enable MDI swapping for RTL8226 where needed

The RTL8226 PHYs in Zyxel XGS1010-10 and XGS1210-10 rev A1 have swapped
MDI lanes. Specify this in the device tree, so the driver can configure
it. With this change, the PHYs no longer require initialization by the
bootloader.
