Subject: [net-next PATCH 0/1 V4] qdisc bulk dequeuing and utilizing delayed tailptr updates
Date: Wed, 24 Sep 2014 18:10:42 +0200 [thread overview]
Message-ID: <20140924160932.9721.56450.stgit@localhost> (raw)
This patch uses DaveM's recent API changes to dev_hard_start_xmit(),
from the qdisc layer, to implement dequeue bulking.
In this V4 iteration we are choosing an conservative approach.
Patch V4:
- Patch rewritten in the Red Hat Neuchatel office jointed work with
Hannes, Daniel and Florian.
- Conservative approach of only using on BQL enabled drivers
- No user tunable parameter, but limit bulking to 8 packets.
- For now, avoid bulking GSO packets packets.
