Subject: [PATCH] examples/ipsec-secgw: fix IPv4 checksum at Tx

[ upstream commit b45be46dfd4548acd8f130841d02e97ab7bc7eb8 ]

For ESP transport and BYPASS mode the app might generate output
packets with invalid IPv4 header checksum.
At least such behavior was observed on few Intel NICs.
The reason is that the app didn't set ipv4 header checksum to zero
before passing it to the HW.

Fixes: 906257e965b7 ("examples/ipsec-secgw: support IPv6")
