This patchset updates mlxsw to use a new firmware version and adds
support for split into two ports on Spectrum-2 based systems.
Patch #1 updates the firmware version to 13.2000.1122
Patch #2 queries new resources from the firmware.
Patch #3 makes use of these resources in order to support split into two
ports on Spectrum-2 based systems. The need for these resources is
explained by Shalom:
When splitting a port, different local ports need to be mapped on different
systems. For example:
SN3700 (local_ports_in_2x=2):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 5
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 3
front panel 2 --> local port 5
SN3800 (local_ports_in_2x=1):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 3
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 2
front panel 2 --> local port 3
The local_ports_in_{1x, 2x} resources provide the offsets from the base
local ports according to which the new local ports can be calculated.
