Working hardware flow offload for MT7620

Excuse me, I tried to compile this firmware for TP-Link Archer C5 v4, but I don't know why there is no local network card.

serial port tty:

ifconfig -a
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
...
wlan0     Link encap:Ethernet  HWaddr 20:6B:E7:F7:62:
...
wlan1     Link encap:Ethernet  HWaddr 20:6B:E7:F7:62:
...

The compilation steps I used:

wget https://github.com/anlix-io/openwrt/archive/refs/tags/v19.07.8-ANLIX.tar.gz
tar -xf v19.07.8-ANLIX.tar.gz
cd openwrt-19.07.8-ANLIX/

./scripts/feeds update -a
./scripts/feeds install -a

make defconfig
make menuconfig #set Target System: MediaTek Ralink MIPS
                #set Subtarget: MT7620
                #set Target Profile: TP-Link Archer C5 v4
                #set Luci => 1.Collections => Luci 
				kmod-tun
				libcap
				socat
                #set SAVE=>.config =>ok and EXIT
make  -j $(nproc) download 
make  -j $(nproc) V=s

Is the implantation still alive? Is there support for newer kernels, e.g. 5.15?

You might be missing the ralink/mediatek Ethernet driver (or it failed to compile). Check dmesg.
