ethernet: fix DMAC check and skip unnecessary ones (VPP-1868)

Fix and optimize DMAC check in ethernet-input node to utilize NIC or
driver which support L3 DMAC-filtering mode so that DMAC check can be
bypassed safely for interfaces/sub-interfaces in L3 mode.
Checking of interface in L3-DMAC-filtering state to avoid DMAC check
require the following:
a) Fix interface driver init sequence for devices which supports L3
DMAC-filtering to indicate its capability and initialize interface
to L3 DMAC-filtering state.
b) Fix ethernet_set_flags() function and its associated callback
flags_change() functions registered by various drivers in interface
infra to provide proper L3 DMAC filtering status.
Maintain interface/sub-interface L3 config count so DMAC checks can be
bypassed if L3 forwarding is not setup on any main/sub-interfaces.

Type: fix
Ticket: VPP-1868

rdma: introduce direct verb for Cx4/5 tx

Direct Verb allows for direct access to NIC HW rx/tx rings. This patch
introduce TX direct verb support for Mellanox ConnectX-4/5 adapters.
'dv' mode must be explicitely selected at interface creation to benefit
from this.

rdma: api: prepare support for direct verb

Prepare rdma interface creation API for direct verb support:
- add new optional 'mode' parameters to select between ibverb or direct
verb backend (optional, default to 'auto')
- set default value for rxq_num (1), rxq_size (1024) and txq_size
(1024) so they are now optional
- bump default create value for rxq_size and txq_size to 1024 if
unset (0) so they are coherent with default values above

rdma: add support for promiscuous mode

rdma interfaces filter packets per MAC by default to share the physical
interface between multiple users (eg. VPP and Linux).
When configured in promiscuous mode, all packets will go to this
interface, regardless of the MAC. All other interface will not receive
anymore packet while it is in promiscuous mode.
Promiscuous mode is needed (and automatically turned on) for L2 path
(l2patch, xconnect, bridge...).

Add RDMA ibverb driver plugin

RDMA ibverb is a userspace API to efficiently rx/tx packets. This is an
initial, unoptimized driver targeting Mellanox cards.
Next steps should include batching, multiqueue and additional cards.
