Subject: [Intel-wired-lan] [next PATCH 0/4] i40e/i40evf: Improve throughput by reducing PCIe overhead
Date: Wed, 17 Feb 2016 11:02:37 -0800 [thread overview]
Message-ID: <20160217185838.10339.68543.stgit@localhost.localdomain> (raw)
This patch series is meant to address some minor performance issues and to
improve the throughput for the adapter.
On my system I saw a .5Gbps improvement based on these patches.
Specific items addressed include the use of modulo division in the Tx
fast-path, redundant checks against CHECKSUM_PARTIAL, and the use of only
8K of data per TXD when the maximum supported value is 16K - 1.

i40e/i40evf: Break up xmit_descriptor_count from maybe_stop_tx
i40e/i40evf: Rewrite logic for 8 descriptor per packet check
i40e/i40evf: Move Tx checksum closer to TSO
i40e/i40evf: Allow up to 12K bytes of data per Tx descriptor instead of 8K
