Subject: [dpdk-dev] [PATCH v2 5/7] ipsec: move inbound and outbound code into different files
Date: Wed, 20 Mar 2019 17:24:37 +0000	[thread overview]
Message-ID: <1553102679-23576-6-git-send-email-konstantin.ananyev@intel.com> (raw)
Message-ID: <20190320172437.eHRNc1e9lq2ov4G3J2es4tQc003-wsqcOE9_Y8FMmLo@z> (raw)
In-Reply-To: <1551381661-21078-1-git-send-email-konstantin.ananyev@intel.com>

sa.c becomes too big, so decided to split it into 3 chunks:
 - sa.c - control path related functions (init/fini, etc.)
 - esp_inb.c - ESP inbound packet processing
 - esp_outb.c - ESP outbound packet processing

Plus few changes in internal function names to follow the same
code convention.
No functional changes introduced.
