Johnson Li,
Thanks for the second version of the patch.
As project lead for both the OpenDaylight SFC and the OPNFV SFC
projects, I am very interested in this functionality being merged into
OVS. In OPNFV SFC, we have done extensive testing with previous forked
versions of the OVS NSH
Is the current implementation really dependent on Simon's patch?
I understood that the current implementation is for ethernet+NSH and
VXLAN+ethernet+NSH which doesnt require Simon's patch. Simon's patch
would be needed for VXLAN-GPE+NSH, which is not in this implementation.
Maybe the authors c
I am Lt.Gen Natalia. Jordan Williams i will like to have a little discussion
