Subject: [PATCH net-next 13/17] mlxsw: spectrum_fid: Add profile_id to flood profile

In the CFF mode, flood profiles are identified by a unique numerical
identifier. This is used for configuration of FIDs and for configuration of
traffic-type to PGT offset rules. In both cases, the numerical identifier
serves as a handle for the flood profile. Add the identifier to the flood
profile structure.

There is currently only one flood profile in use explicitly, the one used
for all bridging. Eventually three will be necessary in total: one for
bridges, one for rFIDs, one for NVE underlay. A total of four profiles
are supported by the HW. Start allocating at 1, because 0 is currently
used for underlay NVE flood.
