This patchset try to fix bpf_redirect to ifb netdev.
Prevent packets loopback and perfromance drop, add check
in sch egress.

Please provide a changelog in the cover letter. With the links to
your previous versions ideally.
Otherwise it becomes difficult to understand what are the changes
between them.

Hi Alexander
This version of patchset, 2/3 only updates the commit message. because the
example in the commit message is not a usual case.
There are no  comments, so I sent them again.
I will provide a changelog in the next version or resend this version
again.  Thanks.
