Subject: [ar7] fallback to "dumb switch" mode if no PHY was detected
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fsvn-archive%2Farchive.git;a=commitdiff_plain;h=ca86961bccaa52f51537f10ae3974938c0b580b7;hp=d64dc849b940a2bd82c96f65c363cd8d0cfcf7ce

[ar7] fallback to "dumb switch" mode if no PHY was detected

This will enable the second Ethernet MAC in most cases, but will allow
previously non working devices to work.
