Hey, last night I pushed in the essential offloading support changes for IPv6 along with quite a bit of other "noise" into HEAD. There is more locking improvements etc. to come once I have looped things back to my working tree and Michael Tuexen will improve SCTP/v6 on loopback as well soonish. This is a call for testing. The in-tree cxgb(4) and ixgbe(4) drivers have been updated to make use of the new features (TSO6/LRO6), and more drivers will follow (I already have cxgbe done, talking about mxge, ..) but others should also see improvements for at least upper layer protocol checksum calculations and I'd love people to test with as many drivers as possible, as I plan to merge it for the upcoming 9.1-RELEASE cycle and wouldn't want to ship broken IPv6 in a few months;-) Here's the patch that should just apply to stable/9 matching what I put into HEAD (+ an earlier cxgb change) (untested): http://people.freebsd.org/~bz/20120525-01-ipv6-offload-mfc9.diff If you need a patch for a specific release please drop me a private email and I'll try to publish one (8.2 and up only though most likely). Please test and report to me or net@. Thanks /bz PS: we now also disallow LRO automatically if forwarding is turned on, just in case you wonder; a change that should have been done years ago;-) -- Bjoern A. Zeeb You have to have visions! It does not matter how good you are. It matters what good you do!
