REPLY_MSG_ID_BASE is the standard way to define reply message id base,
so this refactor makes all the files use that. This is a preparation
patch for future safety add-ons which rely on REPLY_MACRO* parameters to
be preprocessor tokens identifying the message instead,

When switching to the direct verb chain buffer tx path, we must account
for all remaining packets, including the packets that would wrapped
around.
Previously we were using the 'n' counter but ignoring the 'n_wrap'
counter: if some packets would have wrapped around in the default path,
it would be ignored by the chained buffer tx path.
Compute the correct number of remaining packets based on the old and
current txq tail instead.
Also simplify the chained tx function parameters.

Current rdma input L3 validating behavior for scalar path is:
if any packet L3_OK flag matches, then unset skip_ip4_cksum.
The correct behavior should be if any packet L3_OK NOT match,
then unset skip_ip4_cksum. The logic is also different from
the vector path. This patch fixes the wrong behavior for scalar path.

This change leverages the striding RQ feature of
ConnectX-5 adapters to support chained buffers on
the RX path. In Striding RQ mode, WQE are SG lists
of data segments, each mapped to a vlib_buffer.
When a packet is received, it can consume one or
multiple data segments belonging to the WQE,
without wasting the whole WQE.

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.

Fix a bug that caused some input packets to be dropped due to errors of
the type 'ip4 length > l2 length'. The change is related to the second
call to the rdma_device_input_bufs() function that happens when the end
of the ring buffer is reached.

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
