Kernel Version：5.4.65 A bug where ip route fails

For Developers
1 
ip rule add from 192.168.6.187 table 10
ip route add default via 10.0.0.1 dev tun0 table 10

In previous versions,

ip rule add from 192.168.6.187 table 10
ip route add default via 10.0.0.1 dev tun0 table 10

You can let its 192.168.6.187 use the tun0 network card,

I updated openwrt to 5.4.65

After that, appeared

ip rule add from 192.168.6.187 table 10
ip route add default via 10.0.0.1 dev tun0 table 10

Unable to connect.
This does not exist in the previous version.

After testing with my other equipment,

This bug also appeared。

I can't use it now

ip rule add from 192.168.6.187 table 10
ip route add default via 10.0.0.1 dev tun0 table 10
To determine whether a specific machine uses a virtual network card, and hope to solve it as soon as possible.
I rolled back the previous version, which is normal.

The function introduced here is invalid and the display cannot be connected, but there is no problem in the previous version.
