Subject: [PATCH net-next 05/12] ipv4: ip_tunnel: Unmask upper DSCP bits in ip_tunnel_bind_dev()
Date: Thu, 5 Sep 2024 19:51:33 +0300	[thread overview]
Message-ID: <20240905165140.3105140-6-idosch@nvidia.com> (raw)
In-Reply-To: <20240905165140.3105140-1-idosch@nvidia.com>

Unmask the upper DSCP bits when initializing an IPv4 flow key via
ip_tunnel_init_flow() before passing it to ip_route_output_key() so that
in the future we could perform the FIB lookup according to the full DSCP
value.
