[PATCH v5 0/2] fix two issues and optimize code on tpacket_snd()

Posted by Yun Lu 2 months, 3 weeks ago

From: Yun Lu <luyun@kylinos.cn>

This series fix two issues and optimize the code on tpacket_snd():
1, fix the SO_SNDTIMEO constraint not effective due to the changes in
commit 581073f626e3;
2, fix a soft lockup issue on a specific edge case, and also optimize
the loop logic to be clearer and more obvious;
