Subject: [dpdk-dev] [PATCH 0/4] cxgbe: latency and performance fixes
Date: Sat, 27 May 2017 09:17:56 +0530 [thread overview]
Message-ID: <cover.1495856647.git.rahul.lakkireddy@chelsio.com> (raw)
This series of patches rework TX and RX path to reduce latency
and improve performance.
Patch 1 reduces latency for slow traffic by using status page update
on RX path to process batch of packets and improves coalesce TX path
to handle slow moving traffic.
Patch 2 fixes an issue with RXQ default parameters not being applied
to all ports under same PF.
Patch 3 fixes rmb bottleneck in RX path.
Patch 4 adds ability to configure PCIe extended tags.
This series depend on following series:
"cxgbe: add support for Chelsio T6 family of adapters"
Thanks,
Rahul
