Every new HCA VF will be identified with this device ID.

Allow more macro arguments and split the variable type and name into
separate arguments. This allows simple and powerful copy and extraction
of values from IFC based structures into SYSCTLs with the use of a single
macro.

Implement a watchdog as part of the healtcare subsystem which
reads the PCI power status during startup and upon the PCI
power status change event and store it into the core device
structure. This value is then exported to user-space via a
read-only SYSCTL. A dmesg print has been added to inform
the admin about the PCI power status.

CM layer calls ib_modify_port() regardless of the link layer.
For the Ethernet ports, qkey violation and Port capabilities
are meaningless. Therefore, always return success for ib_modify_port
calls on the Ethernet ports.

If generation is cleared due to hardware clock failure, check for it before
the divisor is used. Actually clear generation when failure occurs.
While there, stop doing the calculations inside the generation loop. Since
all members of mlx5e_clbr_point are used for calculations, get the
local copy of the structure and use it after generation stabilized.

The physical- and virtual- port counters might not reflect the amount
of data received after address filtering. Use the software counters
instead for rx_packets and rx_bytes to know exactly how much data
was received.

Add mlx5 implementation for the ones defined by the mlxfw
shared module to be used while flashing the device firmware.
The callbacks do their job through the MCQI, MCC and MCDA registers.

The current mapping of driver counters to netstat counters is wrong.
For example, a single jabber packet, will cause the Ierrs counter to
count three times.
The work for mapping the hardware and software counters to their right
place in netstat counters were already done in Linux, take that as is
to the FreeBSD driver.

ib_req_notify_cq may return negative value which will indicate a
failure. In the case of uncorrectable error, we will end up in an
endless loop. Fix that, by going to another loop with poll_more
only if there is anything left to poll.

PCAM: Ports capabilities mask register.

PCAM and MCAM registers will provide information regarding firmware
support for different features, in order to avoid cases where new driver
combined with old firmware results in syndromes (for ex. PCIe counters
before this patchset).

Today mlx5 devices support two teardown modes:
1- Regular teardown
2- Force teardown
This change introduces the enhanced version of the "Force teardown" that
allows SW to perform teardown in a faster way without the need to reclaim
all the pages.
Fast teardown provides the following advantages:
1- Fix a FW race condition that could cause command timeout
2- Avoid moving to polling mode
3- Close the vport to prevent PCI ACK to be sent without been
scattered to memory
