When software sends commands to firmware using the host
slave command interface, firmware fails to receive the
command due to a checksum failed error, as the checksum is
not being correctly set by the driver software.
This patch sets command checksum to the default value of
0xFF, as per the datasheet, therefore the checksum won't
be checked by firmware.

This commit brings back Rx scatter and related support by the MTU update
function. The maximum number of segments per packet is not a fixed value
anymore (previously MLX5_PMD_SGE_WR_N, set to 4 by default) as it caused
performance issues when fewer segments were actually needed as well as
limitations on the maximum packet size that could be received with the
default mbuf size (supporting at most 8576 bytes).
These limitations are now lifted as the number of SGEs is derived from the
MTU (which implies MRU) at queue initialization and during MTU update.

The primary purpose of rxq_rehash() function is to stop and restart
reception on a queue after re-posting buffers. This may fail if the array
that temporarily stores existing buffers for reuse cannot be allocated.
Update rxq_rehash() to work on the target queue directly (not through a
template copy) and avoid this allocation.
rxq_alloc_elts() is modified accordingly to take buffers from an existing
queue directly and update their refcount.
Unlike rxq_rehash(), rxq_setup() must work on a temporary structure but
should not allocate new mbufs from the pool while reinitializing an
existing queue. This is achieved by using the refcount-aware
rxq_alloc_elts() before overwriting queue data.

Compared to its previous incarnation, the software limit on the number of
mbuf segments is no more (previously MLX5_PMD_SGE_WR_N, set to 4 by
default) hence no need for linearization code and related buffers that
permanently consumed a non negligible amount of memory to handle oversized
mbufs.
The resulting code is both lighter and faster.
With the addition of this code, older GCC versions (such
as 4.8.5) may complain about 'wqe' variable being uninitialized, so
initialize it preemptively, even though it is not necessary to do so.

Mini (compressed) completion queue entries (CQEs) are returned by the
NIC when PCI back pressure is detected, in which case the first CQE64
contains common packet information followed by a number of CQE8
providing the rest, followed by a matching number of empty CQE64
entries to be used by software for decompression.
Before decompression:
0 1 2 6 7 8
+-------+ +---------+ +-------+ +-------+ +-------+ +-------+
| CQE64 | | CQE64 | | CQE64 | | CQE64 | | CQE64 | | CQE64 |
|-------| |---------| |-------| |-------| |-------| |-------|
| ..... | | cqe8[0] | | | . | | | | | ..... |
| ..... | | cqe8[1] | | | . | | | | | ..... |
| ..... | | ....... | | | . | | | | | ..... |
| ..... | | cqe8[7] | | | | | | | | ..... |
+-------+ +---------+ +-------+ +-------+ +-------+ +-------+
After decompression:
0 1 ... 8
+-------+ +-------+ +-------+
| CQE64 | | CQE64 | | CQE64 |
|-------| |-------| |-------|
| ..... | | ..... | . | ..... |
| ..... | | ..... | . | ..... |
| ..... | | ..... | . | ..... |
| ..... | | ..... | | ..... |
+-------+ +-------+ +-------+
This patch does not perform the entire decompression step as it would be
really expensive, instead the first CQE64 is consumed and an internal
context is maintained to interpret the following CQE8 entries directly.
Intermediate empty CQE64 entries are handed back to HW without further
processing.

For performance reasons, this patch uses 2 VIC RQs per RQ presented to
DPDK.
The VIC requires that each descriptor be marked as either a start of
packet (SOP) descriptor or a non-SOP descriptor. A one RQ solution
requires skipping descriptors when receiving small packets and results
in bad performance when receiving many small packets.
The 2 RQ solution makes use of the VIC feature that allows a receive
on primary queue to 'spill over' into another queue if the receive is
too large to fit in the buffer assigned to the descriptor on the
primary queue. This means that there is no skipping of descriptors
when receiving small packets and results in much better performance.
