Subject: examples/ipsec-secgw: update event mode inline path
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ea28ab889ea65d943f3a9c8a5344c5bb75733e9f;p=dpdk.git

examples/ipsec-secgw: update event mode inline path

Update mbuf.l2_len with L2 header size for outbound
inline processing.

This patch also fixes a bug in arg parsing.
