Subject: econet: en7528: fix swapped WiFi eeprom references for DASAN H660GM-A
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3fe9307c14f9da57082c80c607c98c8f4ac3ea53;p=thirdparty%2Fopenwrt.git

econet: en7528: fix swapped WiFi eeprom references for DASAN H660GM-A

The 2.4 GHz and 5 GHz WiFi eeprom cell references were assigned to the
wrong PCIe slots. Swap them so slot0 (2.4 GHz) uses the eeprom at
0x1c0000 and slot1 (5 GHz) uses the eeprom at 0x40000. Fix the eeprom
cell lengths to match the sizes expected by their respective drivers.
