There are multiple occasions where Netfilter code needs to perform route lookups and initialise struct flowi4. As we're in the process of converting the .flowi4_tos field to dscp_t, we need to convert the users so that they have a dscp_t value at hand, rather than a __u8. All netfilter users get the DSCP (TOS) value from IPv4 packet headers. So we just need to use the new ip4h_dscp() helper to get a dscp_t variable. Converting .flowi4_tos to dscp_t will allow to detect regressions where ECN bits are mistakenly treated as DSCP when doing route lookups.
