Subject: fallback to "dumb switch" mode if no PHY was detected
X-Git-Tag: reboot~20797
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ac0b6ee5596fcede180f1c0fcc013e1b73160fb8;p=openwrt%2Fstaging%2Fchunkeey.git

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.
