mlxsw: spectrum_fid: Configure flooding table type for rFID

Browse source

Using unified bridge model, RITR register no longer configures the rFID
used for sub-port RIFs. It needs to be created by software via SFMR. Such
FIDs need to be created with a special flood indication using
'SFMR.flood_rsp=1'. It means that for such FIDs, router sub-port flooding
table will be used, this table is configured by firmware.

Set the above mentioned field as part of FID initialization and FID
edition, so then when other fields will be updated in SFMR, this field
will store the correct value and will not be overwritten.

Add 'flood_rsp' variable to 'struct mlxsw_sp_fid_family', set it to true
for rFID and to false for the rest.
