Subject: [PATCH net-next v2 02/12] ipv4: Unmask upper DSCP bits in ip_route_output_key_hash()
Date: Thu, 29 Aug 2024 09:54:49 +0300 [thread overview]
Message-ID: <20240829065459.2273106-3-idosch@nvidia.com> (raw)
In-Reply-To: <20240829065459.2273106-1-idosch@nvidia.com>
Unmask the upper DSCP bits so that in the future output routes could be
looked up according to the full DSCP value.
