Message-ID: <40680C535D6FE6498883F1640FACD44D011432D2@ka-exchange-1.kontronamerica.local> Date: Mon, 16 Jul 2012 13:02:37 -0700 From: "Andy Cress" <andy.cress@...kontron.com> To: <netdev@...r.kernel.org> Subject: [PATCH 0/4] pch_gbe: avoiding transmit timeouts (rev 2) 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-the-checksum-fill-to-the-error-location.patch 0002-pch_gbe-fix-transmit-watchdog-timeout.patch 0003-pch_gbe-add-extra-clean-tx.patch (includes bumping the version to 1.01) 0004-pch_gbe-vlan-skb-len-fix.patch This rev2 has the following changes: 0001: tested w skb_checksum_start_offset, but cannot use it here, added comment 0004: delete transmit length error check as unnecessary 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.
