From: Rafał Miłecki <rafal@xxxxxxxxxx>
So far we had a property for "ethaddr" NVMEM cell containing base
Ethernet MAC address. The problem is vendors often pick non-standard
names for storing MAC(s) (other than "ethaddr"). A few names were
noticed over years:
1. "wanaddr" (Edimax, ELECOM, EnGenius, I-O DATA, Sitecom)
2. "et1macaddr" (ASUS)
3. "eth1addr" (Buffalo)
4. "athaddr" (EnGenius)
5. "baseMAC" (Netgear)
6. "mac" (Netgear)
7. "mac_addr" (Moxa)
and more ("HW_LAN_MAC", "HW_WAN_MAC", "INIC_MAC_ADDR", "LAN_MAC_ADDR",
"RADIOADDR0", "RADIOADDR1", "WAN_MAC_ADDR", "lan1_mac_addr", "wanmac",
"wmac1", "wmac2").
It doesn't make sense to add property for every possible MAC cell name.
Instead allow specifying cells with "mac" compatible.
