Subject: examples/ipsec-secgw: fix AES-CTR block size
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8d9a222507b291113e18e6bc46f3196a51fd181d;p=dpdk.git

examples/ipsec-secgw: fix AES-CTR block size

This patch fixes the incorrect block size for AES-CTR in
legacy mode. Originally, wrong block size will cause
esp_inbound() drop AES-CTR encrypted packets if the payload
sizes not equal to multiple times of 16.

Fixes: 4470c22de2e1 ("examples/ipsec-secgw: add AES-CTR")
