Subject: [PATCH 22/23] netfilter: nf_tables: performance set policy skips size description in selection
Date: Tue,  7 Nov 2017 01:52:12 +0100	[thread overview]
Message-ID: <20171107005213.22618-23-pablo@netfilter.org> (raw)
In-Reply-To: <20171107005213.22618-1-pablo@netfilter.org>

Use the complexity and space notations if policy is performance, this
results in placing the bitmap set representation over the hashtable for
key <= 16 for better performance as we discussed during the last NFWS in
Faro, Portugal.
