Subject: ar71xx: connect GMAC0 to the internal switch on DB120
X-Git-Url: https://git.rohieb.name/openwrt.git/commitdiff_plain/12930c327277529df91133ead16a28046a48047a?hp=ba503544374858022cd08d28e6e6f7bf64bdb615

ar71xx: connect GMAC0 to the internal switch on DB120

Because the external switch has no driver yet, connect GMAC0
to the PHY4 of the internal switch for now. This allows to
use the DB120 board as a router with 4LAN+1WAN ports.
