From 47afa284b96c62bda127604e6091fd5c9fd7e42c Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 29 Aug 2024 09:54:48 +0300 Subject: ipv4: Unmask upper DSCP bits in RTM_GETROUTE output route lookup Unmask the upper DSCP bits when looking up an output route via the RTM_GETROUTE netlink message so that in the future the lookup could be performed according to the full DSCP value. No functional changes intended since the upper DSCP bits are masked when comparing against the TOS selectors in FIB rules and routes.
