Subject: [PATCH net-next] net: mana: Set default number of queues to 16
Date: Fri, 20 Mar 2026 16:30:27 -0700 [thread overview]
Message-ID: <20260320233027.1603495-1-longli@microsoft.com> (raw)
Set the default number of queues per vPort to MANA_DEF_NUM_QUEUES (16),
as 16 queues can achieve optimal throughput for typical workloads. Users
can increase the number of queues up to max_queues via ethtool if needed.
Signed-off-by: Long Li <longli@microsoft.com>
