I compiled 10.6 kernel 4.19.152 with your MR patch and tested on our
setup. I can confirm no more regression issue is found on both network
setup we use (bonding and non-bonding).

As for the NET_SWITCHDEV we have this enabled in our production machine
from kernel compiled in 10.3 with this patch. And its been running for 2
months or so without any issue.

Please consider merging this patch and release it as part of Debian 10.7
release.

Cheers,
Vasudev
