Hi, Nir. Patches seems OK in general, though I didn't look very close.
It would be great to have them tested by other vendors.
Ian, Emma, may I ask you to verify that this change doesn't break offloading
with Intel NICs?
Best regards, Ilya Maximets.
Tested this series on Intel NICs and doesn't break any existing offload support.
Intel NICs do not support offloading of GRE flows.
Tested-by: Emma Finn <emma.f...@intel.com>
Thanks,
Emma
