Subject: [PATCH 4/5] net/ice: add option to download scheduler topology
Date: Wed, 9 Oct 2024 18:08:21 +0100 [thread overview]
Message-ID: <20241009170822.344716-5-bruce.richardson@intel.com> (raw)
In-Reply-To: <20241009170822.344716-1-bruce.richardson@intel.com>
The DDP package file being loaded at init time may contain an
alternative Tx Scheduler topology in it. Add driver option to load this
topology at init time.
