net/mlx5: support matching GRE optional fields

This patch adds matching on the optional fields (checksum/key/sequence)
of GRE header. The matching on checksum and sequence fields requests
support from rdma-core with the capability of misc5 and tunnel_header 0-3.

For patterns without checksum and sequence specified, keep using misc for
matching as before, but for patterns with checksum or sequence, validate
capability first and then use misc5 for the matching.

net/mlx5: fix E-Switch manager vport ID

One of the E-Switch vports plays the special role - it is assigned as
"E-Switch manager" and has some special exclusive rights and duties - it
maintains all the representors, manages FDB domain flows, etc. By
default, the E-Switch vport index was supposed to be zero on standalone
NICs (regular ConnectX) and 0xFFFE SmartNIC (BlueField), but that was
not always correct - this index can be assigned with any value by
kernel/hypervisor.

Currently the E-Switch manager vport id is supposed to be default - 0
for standalone NICs, and 0xFFFE for the SmartNICs, and is deduced from
the device PCI id.

To handle this and do not suggest any default values, can use DevX API
to query E-Switch manager vport ID directly from the firmware during
initialization, and use that value by default. If the new method is not
provided (legacy firmware), fallback to use the PCI id approach.

common/mlx5: fix queue pair ack timeout configuration

VDPA driver creates two QPs(1 queue pair include 1 send queue
and 1 receive queue) per virtio queue to get traffic events
from NIC to SW.
Two QPs(called FW QP and SW QP) are created as loopback QP
and FW QP'SQ is connected to SW QP'RQ internally.

When packet receive or send out, HW will send WQE by FW QP'SQ,
then SW will get CQE from the CQ of SW QP.

With large scale and heavy traffic, the SQ's request may fail
to get ACK from RQ HW, because HW is busy.
SQ will retry the request with qpc.retry_count times and each time
wait for 4.096 uS *2^(ack_timeout) for the response. If still can’t
get RQ’s HW response, SQ will go to an error state.

16 is experienced value. It should not be too high or too low.
Too high will make QP waits too long in case it’s packet drop.
Too low will cause QP to go to an error state(retry-exceeded) easily.

net/mlx5: support Rx queue delay drop

For the Ethernet RQs, if there all receiving descriptors are
exhausted, the packets being received will be dropped. This behavior
prevents slow or malicious software entities at the host from
affecting the network. While for hairpin cases, even if there is no
software involved during the packet forwarding from Rx to Tx side,
some hiccup in the hardware or back pressure from Tx side may still
cause the descriptors to be exhausted. In certain scenarios it may be
preferred to configure the device to avoid such packet drops,
assuming the posting of descriptors will resume shortly.

To support this, a new devarg "delay_drop" is introduced. By default,
the delay drop is enabled for hairpin Rx queues and disabled for
standard Rx queues. This value is used as a bit mask:
- bit 0: enablement of standard Rx queue
- bit 1: enablement of hairpin Rx queue
And this attribute will be applied to all Rx queues of a device.

The "rq_delay_drop" capability in the HCA_CAP is checked before
creating any queue. If the hardware capabilities do not support
this delay drop, all the Rx queues will still be created without
this attribute, and the devarg setting will be ignored even if it
is specified explicitly. A warning log is used to notify the
application when this occurs.

common/mlx5: support basic receive memory pool

The hardware Receive Memory Pool (RMP) object holds the destination for
incoming packets/messages that are routed to the RMP through RQs. RMP
enables sharing of memory across multiple Receive Queues. Multiple
Receive Queues can be attached to the same RMP and consume memory
from that shared poll. When using RMPs, completions are reported to the
CQ pointed to by the RQ, and this Completion Queue can be shared as
well.

This patch adds DevX supports of PRM RMP object.
