Hi Venu,
You should be able to but not through vcl, as is, because the stack doesn’t
have any transport that’s equivalent to “raw sockets”. So your options would be
to either use memif or to write a new host stack transport that passes raw
packets to apps and integrate it with vcl and the component that classifies
traffic.
Note that we used to have an sctp transport but it was deprecated for lack of
maintenance. If anybody wants to pick up the maintenance work, it could be
revived.
Regards,
Florin
