Subject: examples/ipsec-secgw: fix build with gcc 4.5
X-Git-Tag: spdx-start~6109
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=96362fadd149e5df347c02a9b227e7204487b1ad;p=dpdk.git

examples/ipsec-secgw: fix build with gcc 4.5

GCC 4.5.x does not handle well initializing anonymous union and/or
structs.

To make the compiler happy we name those anonymous union/struct.

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