Subject: [PATCH net-next 1/4] mlxsw: reg: Add "desc" field to SBPR

From: Petr Machata <petrm@...dia.com>

SBPR, or Shared Buffer Pools Register, configures and retrieves the shared
buffer pools and configuration. The desc field determines whether the
configuration relates to the byte pool or the descriptor pool.
