Main changes are 200G support and fixing the definitions of discard and
error counters to match the hardware definitions.
Because the HWRM_PORT_PHY_QCFG message size has now exceeded the max.
encapsulated response message size of 96 bytes from the PF to the VF,
we now need to cap this message to 96 bytes for forwarding. The forwarded
response only needs to contain the basic link status and speed information
and can be capped without adding the new information.
v2: Fix bnxt_re compile error.

Expose out of sequence errors received from FW. This counter is a 32 bit
counter and driver has to accumulate the counter. Stores the previous
value for calculating the difference in the next query.
Also, update the HW statistics structure with new fields.

Broadcom's adapter supports more granular statistics
to allow better understanding about the state of the
chip when data traffic is flowing.
Exposing the detailed stats to the consumer through
the standard hook available in the kverbs interface.
In order to retrieve all the information, driver
implements a firmware command.
