Subject: [PATCH net-next 2/5] ionic: smaller coalesce default
Date: Mon, 31 Aug 2020 16:35:55 -0700	[thread overview]
Message-ID: <20200831233558.71417-3-snelson@pensando.io> (raw)
In-Reply-To: <20200831233558.71417-1-snelson@pensando.io>

We've found that a smaller default value for interrupt coalescing
works better for latency without hurting general operations.
