Subject: ipq806x: Fix gmac1 (WAN) on Netgear D7800
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b163bfbba59b62c05a404e3cc3c59103c93aff68;p=openwrt%2Fstaging%2Fadrian.git

ipq806x: Fix gmac1 (WAN) on Netgear D7800

The WAN port on Netgear D7800 is unable to connect to an ISP when the
link to the modem is running at less than 1GB.

This patch fixes the issue by removing the phy-handle definition
and replacing it with a fixed-link definition

The WAN port is then able to connect to a modem via a link running at 100Mbs or 10Mbs

Fixes: FS#3086
