Subject: [PATCH] wifi: rtw88: rtw8723d: Fix MAC address offset in EEPROM
Date: Thu, 7 Sep 2023 10:09:42 +0200 [thread overview]
Message-ID: <20230907080942.2111305-1-s.hauer@pengutronix.de> (raw)
The MAC address is stored at offset 0x107 in the EEPROM, like correctly
stated in the comment. Add a two bytes reserved field right before the
MAC address to shift it from offset 0x105 to 0x107.
With this the MAC address returned from my RTL8723du wifi stick can be
correctly decoded as "Shenzhen Four Seas Global Link Network Technology
Co., Ltd."
