Hi Erik,

Many thanks for your review.

Regarding Destination MAC rewriting:
- The main goal of Destination MAC rewriting is to make TSN Streams more easy 
to recognize inside the TSN sub-network (at Layer-2). There is always a similar 
interworking pair at the other end of the Stream and it restores the packet to 
its original destination MAC address and VLAN.
Therefore, there is no impact to IP and IP-related traffic that might carry MAC 
addresses, like ARP or NDP.

Thanks for the nits I will fix them.

Thanks
Bala'zs

DISCUSS:
----------------------------------------------------------------------

[[ discuss ]]

[ section 4.1 ]

* I haven't tried to read the IEEE documents referenced here, but I'm
  hoping this question can be easily addressed by those who have.

  Can this Destination MAC rewriting ("replace ... with alternate values")
  ever affect IP and IP-related traffic that might carry MAC addresses,
  like ARP or NDP?

  If there could be impact to MAC-carrying traffic like ARP/NDP then it
  seems likely that more text is required here about that interaction
  (and I should probably figure out how to go read those references
  documents/clauses).
