-Subject: mt76: mt7603: allow eeprom sections starting with 7600
-
-Fixes low signal issue for 2.4 GHz for the TP-Link Archer C50 v4.
-The first two bytes in the eeprom are the chip id. The working
-devices have 0x7628 there, whereas the non-working devices have
-0x7600 there. This chip id gets checked by the function
-mt7603_check_eeprom() which leads the driver to ignore the
-contents of the eeprom partition and load default values from otp.
-
-The has been manually added based on mt76 PR:
-https://github.com/openwrt/mt76/pull/442/
