Please wait until your outstanding submissions get reviewed, here is
the patch review queue for netdev filtered down to your email:

https://patchwork.kernel.org/project/netdevbpf/list/?submitter=222403

Once that's empty you can resume but again please try to go slow.
4 patches under review at a time, start from the most impactful ones.
After you get >20 patches accepted (in networking specifically!) you 
can open up the faucet a bit and go to 10 outstanding patches.
