[Softwires] MTU problem in DS-lite

[Zhen Cao <caozhenpku at gmail.com>]

Hi Alain and All,

I have a question on MTU issue in ipv4-in-ipv6 softwire. I notice
Sec.10.2 of DS-Lite draft has discussed the MTU problem. The draft
introduces one possible way of using TCP MSS option to avoid IP layer
fragmentation and reassembly. It is a good idea but how about the case
for UDP sockets? I suppose there should be a general way to handle the
MTU issue? Thanks for any explanation.

Thanks and regards,
Zhen
