Hi All,

For securing the MSF, (comments from minimal security, thanks for the
input!)

In the next version of MSF, we need to add sentence saying MSF only adapts
the traffic which is secured, practically by checking the DSCP value set
with zero or no, which is in IPv6 header.

In other hands, MSF is a link layer protocol, it doesn't suppose to know
the frame is a IPv6 packet or not. no need to say a field value.

I would like to have some suggestions/comments on this issue.
Does anyone know other way to make the SF not adapt to unsecured traffic
without knowing upper layer field?

Thanks!
Tengfei
