r8152: Add support for MAC address pass through on RTL8153-BD (8e29d23e) · Commits · 戴 / test

RTL8153-BD is used in Dell DA300 type-C dongle. It should be added to the whitelist of devices to activate MAC address pass through. Per confirming with Realtek all devices containing RTL8153-BD should activate MAC pass through and there won't use pass through bit on efuse like in RTL8153-AD. Signed-off-by:
