Subject: [PATCH net-next v3 0/5] ice: allow matching on meta data

Hi,

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.

v2 --> v3: based on Alexander Lobakin comments; link [1]
 * add patch 4 to get rid of anonymous struct initialization
 * few code style changes
 * rename ice_is_rule_info_the_same() and add const params in it
 * avoid holes in ice_adv_rule_info {}

v1 --> v2: link [2]
 * fix spell issues
 * use GENMASK to define source VSI mask

Michal Swiatkowski (5):
  ice: define meta data to match in switch
  ice: remove redundant Rx field from rule info
  ice: allow matching on meta data
  ice: specify field names in ice_prot_ext init
  ice: use src VSI instead of src MAC in slow-path
