Subject: [PATCH 0/4] pch_gbe: avoiding transmit timeouts (rev3)
Date: Thu, 26 Jul 2012 11:57:09 -0400 [thread overview]
Message-ID: <20120726155709.GA10287@telcoserv5> (raw)
When the interface is stressed with 6 VLANs, some transmit timeout stats were
observed, which is a potential precursor to the more severe netdev watchdog
timeout oops. Also we saw more than the expected number of transmit restarts, which impacted performance. The following patches were applied and resolved
the symptom of the transmit timeout stats, and reduced the number of
transmit restarts.
This patch set includes the following patches:
0001-pch_gbe-fix-transmit-watchdog-timeout.patch
0002-pch_gbe-add-extra-clean-tx.patch (includes bumping the version to 1.01)
0003-pch_gbe-vlan-skb-len-fix.patch
This rev3 has the following changes:
* Removed Fix-the-checksum-fill-to-the-error-location.patch for now so Hongbo can evaluate/revise/test based on feedback.
The resulting pch_gbe 1.01 driver has been tested on Kontron Tunnel Creek
EG20T modules and Intel Crown Bay EG20T modules, so I believe that these are
appropriate for consideration in the upstream pch_gbe driver.
Please review and comment.
Thanks,
Andy
