Subject: [PATCH net-next 04/12] ipv4: icmp: Unmask upper DSCP bits in icmp_reply()
Date: Thu, 5 Sep 2024 19:51:32 +0300 [thread overview]
Message-ID: <20240905165140.3105140-5-idosch@nvidia.com> (raw)
In-Reply-To: <20240905165140.3105140-1-idosch@nvidia.com>
Unmask the upper DSCP bits when calling ip_route_output_key() so that in
the future it could perform the FIB lookup according to the full DSCP
value.
