Or. the hw checksum patch was removed from OFED 1.3 I just saw some patches on the mailing list concerning csum offloading. Are these applied in RC3? Or are they going to be introduced in the daily build of tomorrow? Is it correct to state that these patches replace the hw_csum parameter by offloading the csum computation to the mthca? This would mean that the results should be similar also. Does the new offload patch depend on the type of hca being used? According to lspci, we have the InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex (rev a0) card. Do these patches work on a sles 10 sp1 installed on x3755 and x3655 machines of IBM that have this card inserted? Is bonding going to work with this type of offloading?

Hello Eli, ipoib_0030_hw_csum.patch has been removed Would removing this patch cause any errors on applying the rest of patches? If not, I will remove it for our testing as well. Thanks Shirley ___ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg

I don't know where else to find this information. In the Linux model, each change is a patch and each patch is signed, so you should locate the patch and see who is signed on it. This can be done each through using git log or browsing through git web on the relevant tree. In this specific case, you can get a snapshot of ofed 1.3 before the patch was removed, get the tgz of ofa-kernel SRPM and untar it, the look on the directory kernel_patches/fixes it should be there as a patch to patch.
