Subject: [PATCH net-next V2 1/5] net/mlx4_core: Fix QUERY FUNC CAP flags

From: Moshe Shemesh <moshe@...lanox.com>

Separate QUERY_FUNC_CAP flags0 from QUERY_FUNC_CAP flags, as 'flags' is
already used for another set of flags in FUNC CAP, while phv bit should be
part of a different set of flags.
Remove QUERY_FUNC_CAP port_flags field, as it is not in use.

Fixes: 77fc29c4bbbb ('net/mlx4_core: Preparations for 802.1ad VLAN support')
Fixes: 5cc914f10851 ('mlx4_core: Added FW commands and their wrappers for supporting SRIOV')
