According to the cilium thread you linked, this is not anymore an
issue with 5.10.40-1, so I'm marking version already as fixed. 

Can you check with the most current 4.19.225 upstream if this is still
an issue? If so can you report the issue for the 4.19.y branch to
upstream stable (including Daniel Borkmann) and please keep us in the
loop.
