Subject: mvebu: use eth0 as DSA CPU port for Linksys WRT
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4149d2b91c43784ada37efe928c5f6b610c74259;p=openwrt%2Fstaging%2Fyousong.git

mvebu: use eth0 as DSA CPU port for Linksys WRT

eth0 has HW MAC address while eth2 does not.
Use eth0 instead so we don't have to set LAN MAC manually.
Disable unused eth2, until multi CPU port is supported.
