[dpdk-dev] [PATCH 2/8] net/vmxnet3: return unknown IPv4 extension len ptype

[Didier Pallard <didier.pallard@6wind.com>]

Rather than parsing IP header to get proper ptype to return, just return
RTE_PTYPE_L3_IPV4_EXT_UNKNOWN, that tells application that we have an IP
packet with unknown header length.
