Subject: [PATCHv2 net 0/2] Add IP_DSCP_MASK and fix vxlan tos value before xmit

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

Hangbin Liu (2):
  net: add IP_DSCP_MASK
  vxlan: fix getting tos value from DSCP field
