Subject: [PATCH] ramips: mt7621: fix R6850 EEPROM offsets
The Netgear R6850 has its EEPROM data sitting at 0x28000 for the 5
GHz radio
and at 0x20000 for the 2,4 GHz radio. See forum topic for a hex
dump [1].
The commit title/message does not really fit the code changes here.
You are adding full pcieX block, not just swapping EEPROM data.
Please update to make clear what's going on.
I was advised to override the whole block on IRC, rather than just
overriding the &wifi block EEPROM property.
So just overriding that is enough?
Thanks
Stijn
Best
Adrian
