I wonder, if DSA works correctly on all platforms in scenarios where MTU > 1500 is needed and/or encapsulations like Batman. Because both are problematic at least on ramips/mt7621 and RTL8380 for me. Better but still not not right with the current 5.10 testing kernel in master. Maybe related to the bug mentioned here: https://github.com/openwrt/openwrt/pull/4493

I was hoping, that 21.02.0 would still include that one.

In any case, many thanks for all the hard work to everybody involved!
