I tested you patches on the Mikrotik RB750Gr3 and WDR3600 (as I did in 
FS#3866), this time with customized IP-adresses and patches applied to 
For the WDR3600 the issue was fixed, but for the RB750 there is no network.
I was not able to usr IPv6 link-local, OpenWrt default or my 
custom IP-Address.

The Rb750 is DSA, so it seems there is still something wrong. I'll retest with 
current master soon, to rule out issues based on 21.02-rc3.
