[dpdk-dev] [PATCH v3] doc: add new tables for rte flow items and actions support

[Asaf Penso <asafp@nvidia.com>]

In http://doc.dpdk.org/guides/nics/overview.html, table 1.1 lists all
supported features.
It has a single line for "Flow API" that refers to rte_flow support.
rte_flow is composed of many items and actions that are not expressed in
this single line.

The following new tables are suggested:
1. rte_flow items
2. rte_flow actions
3. rte_flow shared actions

Also, since each table needs a new section in the pmd ini
file that might not be relevant for all pmds, the print
error message for missing section in conf.py is removed.

v3:
