Here there are a few formal/process-related mistakes:
- wait at least 24h before posting a new version
- please include the target tree name into the subj prefix
this looks like a fix, so it should possibly target net and include a
'Fixes' tag into the SoB area.
Please be sure to read and follow the process documentation and the
netdev specifics bit from the current kernel source.
Thanks,
Paolo
