Commit Message
From: Kiran Kumar K <kirankumark@marvell.com>
Adding devargs support to parse custom sa action.
Devargs can be specified in the following way.
-a 0002:02:00.0,custom_sa_act=1

With the above configuration, application can enable inline IPsec processing
for 128 outbound SAs.
+- ``Enable custom SA action`` (default ``0``)
+
+ Custom SA action can be enabled by specifying ``custom_sa_act`` ``devargs`` parameter.
+
+ For example::
+
+ -a 0002:02:00.0,custom_sa_act=1
+
+ With the above configuration, application can enable custom SA action. This
+ configuration allows the potential for a MCAM entry to match many SAs,
+ rather than only match a single SA.
+ For cnxk device sa_index will be calculated based on SPI value. So, it will
+ be 1 to 1 mapping. By enabling this devargs and setting a MCAM rule, will
+ allow application to configure the sa_index as part of session create. And
+ later original SPI value can be updated using session update.
+ For example, application can set sa_index as 0 using session create as SPI value
+ and later can update the original SPI value (for example 0x10000001) using
+ session update. And create a flow rule with security action and algorithm as
+ RTE_PMD_CNXK_SEC_ACTION_ALG0 and sa_hi as 0x1000 and sa_lo as 0x0001.
