Subject: [PATCH net-next 1/4] mlxsw: reg: Add "desc" field to SBPR
Date: Mon, 2 May 2022 11:49:23 +0300 [thread overview]
Message-ID: <20220502084926.365268-2-idosch@nvidia.com> (raw)
In-Reply-To: <20220502084926.365268-1-idosch@nvidia.com>
From: Petr Machata <petrm@nvidia.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.
