vxlan: Fix error that was resulting in VXLAN MTU size being 10 bytes too large
This change fixes an issue I found where VXLAN frames were fragmented when they were up to the VXLAN MTU size. I root caused the issue to the fact that the headroom was 4 + 20 + 8 + 8. This math doesn't appear to be correct because we are not inserting a VLAN header, but instead a 2nd Ethernet header. As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the extra headers that are inserted for VXLAN.
