For inline IPsec device, reserve number of rules specified by
``max_ipsec_rules`` and use them while installing rules with
action as security. Rule priority should be 0. If specified
number of rules not available, then only available number of
rules will be allocated and used. If application try to insert
more then allocated rules, flow creation will fail.

+- ``Inline IPsec device flow rules`` (default ``none``)
+
+ For inline IPsec device, reserve number of rules specified by ``max_ipsec_rules``
+ and use them while installing rules with action as security. Rule priority should
+ be 0. If specified number of rules not available, then only available number
+ of rules will be allocated and used. If application try to insert more then
+ allocated rules, flow creation will fail.
+
+ For example::
+
+ -a 0002:1d:00.0,max_ipsec_rules=100
+
+ With the above configuration, 100 rules will be allocated from 0-99 if available
+ and will be used for rules with action security. If 100 rules are not available,
+ and only 50 are available, then only 50 rules will be allocated and used for
+ flow rule creation. If application try to add more than 50 rules, the flow
+ create will fail.
+
- ``SDP device channel and mask`` (default ``none``)
Set channel and channel mask configuration for the SDP device. This
will be used when creating flow rules on the SDP device.

From: Satheesh Paul <psatheesh@marvell.com>
Flow parsing was not handling pattern matching on the
fields of inner VLAN even though MKEX profile could be
extracting inner VLAN fields. Code has been modified
to handle matching fields on two VLAN tags.
