dpdk-plugin: do not request SCTP offload, some cards do not support it while supporting TCP/UDP
The DPDK plugin sets all of the offload flags, which may cause an initialization failure
on the NICs that do not support SCTP offload. The VPP code does not deal with the SCTP
offload at the moment at all, so after discussing with Damjan, we agreed
the best approach to fix the issue is to not request the SCTP offload.
The output of "show hardware" for the NIC in question before this patch:
