Subject: [PATCH nf-next v2 08/10] netfilter: bitwise: only offload boolean operations.
Date: Tue, 14 Jan 2020 21:29:16 +0000
Message-ID: <20200114212918.134062-9-jeremy@azazel.net> (raw)
In-Reply-To: <20200114212918.134062-1-jeremy@azazel.net>

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