From 888ade8f90d7dbbdc8552ae9b23d311f9e61ab0e Mon Sep 17 00:00:00 2001 From: Guillaume Nault Date: Fri, 8 Apr 2022 22:08:37 +0200 Subject: ipv4: Use dscp_t in struct fib_rt_info Use the new dscp_t type to replace the tos field of struct fib_rt_info. This ensures ECN bits are ignored and makes it compatible with the fa_dscp field of struct fib_alias. This also allows sparse to flag potential incorrect uses of DSCP and ECN bits.
