Subject: [dpdk-dev] [PATCH] security: allow application to specify UDP ports to PMD
Date: Thu, 3 Sep 2020 12:12:06 +0530
Message-ID: <20200903064206.16208-1-ktejasree@marvell.com> (raw)

Add UDP source and destination ports in ipsec_xform to allow application
to specify ports to be used for IPsec UDP encapsulation as they are
dynamically changed by NAT in between. Also adding an extra flag to
indicate whether PMD needs to perform encapsulation header verification
in case of inbound. In case of inline IPsec implementation, verification
of outer IP headers and UDP encapsulation headers need to be handled
in the PMD. For lookaside IPsec, application can optionally offload
this to the PMD.
