[PATCH net-next 10/13] mlxsw: spectrum_buffers: Tweak SBMM configuration

[Ido Schimmel]

From: Petr Machata <pe...@mellanox.com>

The SBMM register configures shared buffer allocation and settings for
MC packets according to switch priority. The recommended values are no
reserved buffer and alpha of 1/4, which corresponds to buf_max of 6.
Update mlxsw_sp_sb_mms accordingly.
