Subject: [PATCH 19/21] netfilter: bitwise: only offload boolean operations.
Date: Sat, 18 Jan 2020 21:14:15 +0100	[thread overview]
Message-ID: <20200118201417.334111-20-pablo@netfilter.org> (raw)
In-Reply-To: <20200118201417.334111-1-pablo@netfilter.org>

From: Jeremy Sowden <jeremy@azazel.net>

Only boolean operations supports offloading, so check the type of the
operation and return an error for other types.
