[LEDE-DEV] [PATCH v2] ramips: fix GL-inet GL-MT300N-V2 LAN MAC address

[Kyson Lok]

Here is our customer's issue.

> Flash Openwrt snapshot from https://downloads.openwrt.org/snapshots/targets/ramips/mt76x8/openwrt-ramips-mt76x8-gl-mt300n-v2-squashfs-sysupgrade.bin
>
> Install luci, luci-sqm-app packages
>
> Configure SQM QoS by setting interface name to eth0.2 and entering download and upload speeds (my upload speed is lower than download)
>
> Click Save & Apply
>
> Start a large download or speedtest
>
> Actual results:
>
> Download speed is capped to the upload speed
>
> Expected results:
>
> Download speed should be close to the download speed entered
>
> Stock firmware does not have this bug. In stock firmware (I used 2.27-testing), /etc/config/network contains the section “config device ‘lan_dev’”.
> This section is missing in the Openwrt snapshots. Copying this 3-line section from stock firmware to Openwrt snapshot fixes the bug. The only
> drawback I found is that the MAC address cannot be changed with the luci interface, it can still be changed by editing /etc/config/network.
