Mark Mentovai 565814a5ee ipq806x: ubnt,unifi-ac-hd: reorder eth0 and eth1 ... The Ubiquiti UniFi AC HD (UAP-AC-HD, UAP301) has two Ethernet ports, labeled MAIN and SECONDARY, connected to gmac2 and gmac1, respectively. The standard probe order results in gmac1/SECONDARY being eth0 and gmac2/MAIN being eth1. This does not match the stock firmware, is contrary to user expectation, causes the wrong (high) MAC address to be used in a bridged configuration (the default for this device), and makes the gmac2/MAIN port unusable in the preinit environment (such as for failsafe). Until a recent patch, gmac1/SECONDARY (eth0) was not even usable. This reorders the ports so that gmac2/MAIN is eth0, and the now-working gmac1/SECONDARY is eth1. eth0 has the low MAC address and eth1 has the high; when bridged, the bridge takes on the correct low MAC address. This matches the stock firmware. The MAIN port is usable for failsafe during preinit. This device does not have a switch on board, so there's no possibility to remap ports via switch configuration. "ip link set $interface name" is used instead, during preinit before networking is configured.
