Subject: [PATCH net-next 08/13] mlxsw: Add enumerator for 'config_profile.flood_mode'

From: Amit Cohen <amcohen@...dia.com>

Currently magic constant is used for setting 'flood_mode' as part of
config profile.

As preparation for unified bridge model, which will require different
'flood_mode', add a dedicated enumerator for this field and use it as
part of 'struct mlxsw_config_profile'.

Add the relevant value for unified bridge model.
