2.6.23-stable review patch. If anyone has any objections, please let us know. ------------------ From: Stephen Hemminger <[EMAIL PROTECTED]>
Backport of 8b31cfbcd1b54362ef06c85beb40e65a349169a2 The Marvell Yukon XL chipset appears to have a hardware glitch where it will repeat the checksum of the last packet. Of course, this is timing sensitive and only happens sometimes... More info: http://bugzilla.kernel.org/show_bug.cgi?id=9381 As a workaround just disable hardware checksumming by default on this chip version. The earlier workaround for PCIX, dual port was also on Yukon XL so don't need to disable checksumming there.
