Subject: [PATCH V1 net 2/2] net: ena: fix too long default tx interrupt moderation interval
Date: Mon, 4 Nov 2019 13:58:48 +0200 [thread overview]
Message-ID: <1572868728-5211-3-git-send-email-akiyano@amazon.com> (raw)
In-Reply-To: <1572868728-5211-1-git-send-email-akiyano@amazon.com>
From: Arthur Kiyanovski <akiyano@amazon.com>
Current default non-adaptive tx interrupt moderation interval is 196 us.
This commit sets it to 0, which is much more sensible as a default value.
It can be modified using ethtool -C.
