Subject: ath79: calculate Eth MACs from WLAN on ALFA Network R36A
X-Git-Tag: v21.02.0-rc1~1069
X-Git-Url: http://git.openwrt.org/openwrt/feeds.git?a=commitdiff_plain;h=6d65e3af9b3122e1893d55d1406af286048a1530;p=openwrt%2Fstaging%2Fchunkeey.git

ath79: calculate Eth MACs from WLAN on ALFA Network R36A

New batches of the R36A board series might no longer keep separated
Ethernet MAC addresses stored in flash. Use same approach as on the
N2Q and calculate Ethernet MACs from WLAN one which is kept in ART.
