Use to be we couldnt get the ifb+mirred combo to work
with TSO even without this change - i will have to dig old emails
to remember details. So we are making progress;-> I did write a set
of rules in: Documentation/networking/tc-actions-env-rules.txt
Changli optimized rule #1. When i looked at his patch it seems
to not harm that case. Sometimes dumb is a good principle ;->

cheers,
