net/dpaa2: support VXLAN flow matching

Extracts from vxlan header for distribution.
The vxlan header is set by soft parser code in
soft parser context located from offset 43 of parser results:

<assign-variable name="$softparsectx[0:3]" value="vxlan.vnid"/>

vxlan protocol is identified by vxlan bit of frame attribute flags.
The parser result extracts are added for this functionality.

Example:
flow create 0 ingress pattern vxlan / end actions pf / queue index 4 / end

devtools: check for supported git version

The script devtools/parse-flow-support.sh uses the git-grep
option (-o, --only-matching), which is only supported from
git version 2.19 and onwards.[1]

The script now exits early providing a clear message to the user
about the required git version instead of showing the following
error messages multiple times:
error: unknown switch `o'
usage: git grep [<options>] [-e] <pattern> [<rev>...] [[--] <path>...]

net/bnxt: support tunnel offload

Add support for tunnel offload APIs. Specifically the following
are supported.
tunnel_decap_set, tunnel_match, tunnel_action_decap_release,
tunnel_item_release.

This provides support for VXLAN decap action where two flows
can indicate tunnel offload rule. The first flow indicates the
tunnel properties and second flow indicates the inner packet
structure. The templates are updated to support this
feature.

instead having same layer2 details then it will be rejected.

devtools: check flow API doc tables

The script check-doc-vs-code.sh may be used to add
some automatic checks of the doc.

If run without any argument, a complete check is done.
The optional argument is a git history reference point
to check faster only what has changed since this commit.

In this commit, the only check is for rte_flow tables,
achieved through the script parse-flow-support.sh.
If run without a .ini reference, it prints rte_flow tables.
Note: detected features are marked with the value Y,
while the real .ini file could have special values like I.
The script allow parsing exceptions (exclude or include),
like for bnxt code which lists unsupported items and actions.
