This patch set is aim to update the old IP_TOS_MASK to new IP_DSCP_MASK as tos value has been obsoleted for a long time. But to make sure we don't break any existing behaviour, we can't just replease all IP_TOS_MASK to new IP_DSCP_MASK.

So let's update it case by case. The first issue we will fix is that vxlan is unable to take the first 3 bits from DSCP field before xmit. Use the new RT_DSCP() would resolve this.

v2: Remove IP_DSCP() definition as it's duplicated with RT_DSCP(). Post the patch to net instead of net-next as we need fix the vxlan issue
