Subject: [PATCH v2 net-next 4/4] tcp: Enable 2nd listener hashtable in TCP
Date: Fri, 1 Dec 2017 12:52:32 -0800 [thread overview]
Message-ID: <20171201205232.3012584-5-kafai@fb.com> (raw)
In-Reply-To: <20171201205232.3012584-1-kafai@fb.com>
Enable the second listener hashtable in TCP.
The scale is the same as UDP which is one slot per 2MB.
