42a7f1d774 mlxsw: reg: Extend SBPM register for occupancy control
Since it is not possible to get and clear Port-Pool occupancy data using
SBSR register, there's a need to implement that using SBPM.
Extend pack helper and add unpack helper to get occupancy values.

d81a6bdb87 mlxsw: spectrum: Add IEEE 802.1Qbb PFC support
Implement the appropriate DCB ops and allow a user to configure certain
traffic classes as lossless.

The operation configures PFC for both the egress (respecting PFC frames)
and ingress (sending PFC frames) parts of the port.

At egress, when a PFC frame is received for a PFC enabled priority, then
all the priorities mapped to the same TC are stopped.

At ingress, the priority group (PG) buffers to which the enabled PFC
priorities are mapped are configured to be lossless. PFC frames will be
transmitted when the Xoff threshold is crossed.

The user-supplied delay parameter is used to determine the PG's size
according to the following formula:

PG_SIZE = PG_SIZE_LOSSY + delay * CELL_FACTOR + MTU

In the worst case scenario the delay will be made up of packets that
are all of size CELL_SIZE + 1, which means each packet will require
almost twice its true size when buffered in the switch. We therefore
multiply this value by the "cell factor", which is close to 2.

Another MTU is added in case the transmitting host already started
transmitting a maximum length frame when the PFC packet was received.

As with PAUSE enabled ports, when the port's MTU is changed both the
PGs' size and threshold are adjusted accordingly.

4ec14b7634 mlxsw: Add interface to access registers and process events
Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
the host and the device in order to configure the available device registers.
Another use case is notifications sent from the device to the host,
letting it know about certain events, such as port up / down.

Add the ability to construct EMADs with provisions to construct and
parse the registers' payloads. Implement EMAD transaction layer
which is responsible for the reliable transmission of EMADs. Also, add
an infrastructure used by the switch driver to register for particular
events generated by the device.
