If anyone has any objections, please let me know. ------------------ From: hhorace [ Upstream commit a68b22e2905b04f376e2fa116be5e48b948f81c8 ] According to RFC8325 4.3, Multimedia Streaming: AF31(011010, 26), AF32(011100, 28), AF33(011110, 30) maps to User Priority = 4 and AC_VI (Video). However, the original code remain the default three Most Significant Bits (MSBs) of the DSCP, which makes AF3x map to User Priority = 3 and AC_BE (Best Effort).
