6.6-stable review patch. If anyone has any objections, please let me know.

From: Guillaume Nault gnault@redhat.com
[ Upstream commit 0c30d6eedd1ec0c1382bcab9576d26413cd278a3 ]
Use ip4h_dscp() to get the DSCP from the IPv4 header, then convert the dscp_t value to __u8 with inet_dscp_to_dsfield().
Then, when we'll convert .flowi4_tos to dscp_t, we'll just have to drop the inet_dscp_to_dsfield() call.
