====================
ice: allow matching on meta data

Michal Swiatkowski says:

This patchset is intended to improve the usability of the switchdev
slow path. Without matching on a meta data values slow path works
based on VF's MAC addresses. It causes a problem when the VF wants
to use more than one MAC address (e.g. when it is in trusted mode).

Parse all meta data in the same place where protocol type fields are
parsed. Add description for the currently implemented meta data. It is
important to note that depending on DDP not all described meta data can
be available. Using not available meta data leads to error returned by
function which is looking for correct words in profiles read from DDP.

There is also one small improvement, remove of rx field in rule info
structure (patch 2). It is redundant.
