Subject: [RFC net-next PATCH 0/4] qlge: Performance changes for qlge.
Date: Mon, 17 Aug 2009 14:08:45 -0700 [thread overview]
Message-ID: <1250543329-15123-1-git-send-email-ron.mercer@qlogic.com> (raw)
All,
Looking for feedback on changes for qlge. The goal is to:
1) Do TX completions in send path (with cleaner timer).
2) Change RSS queue count to match MSIx vector count instead
of CPU count. Some platforms didn't offer enough vectors
for our previous approach.
3) Change large RX buffer logic to use either multiple pages
or chunks of pages based on MTU and system page size.
Examples:
64k Pages with 1500 MTU. The RX buffers size would be
2048 bytes and there would be 32 per page.
4k pages with 9000 MTU. The RX buffer size would be 16k,
or 4 pages per buffer.
Regards,
Ron Mercer
