GSO support by PMD drivers

GSO support by PMD drivers

[Vadim Suraev]

Hi, all,
I found ixgbe in couple with rte_mbuf (and probably other PMD drivers)
don't support GSO, I reverse engineered the linux kernel's  ixgbe's gso
support and got it working in 1.6. Could it be useful to provide the patch?
Regards,
 Vadim.

LSO/TSO support is an important feature, I'm surprised its not
supported in DPDK.
I personally would like to see these patches.

I already submitted a patch providing segmentation offload a few months
ago:
http://dpdk.org/ml/archives/dev/2014-May/002537.html

A part of this series has been reworked by Bruce and is now integrated
in head. I think rebasing the rest of the series should not be too
difficult since Bruce's work is based on this series. Unfortunately,
I won't have time to do the rebase by myself in the coming weeks, but
feel free to do it if you need this feature.

Regards,
Olivier
