[j-nsp] port mirror to multiple ports on MX80 in inet6

[Clarke Morledge]

Paul,

Just to come full circle on that IRB issue and L2 port mirroring.  From 
page 213 in Hanks and Reynolds _Juniper MX Series_:

"If the packet's L2 destination MAC matches the router's IRB MAC 
address.... Its important to note that any bridge family filters applied 
to the related Layer 2 IFLs, or to the FT [forwarding table] in the BD 
itself, are not evaluated or processed for routed traffic, even though 
that traffic may ingress on a Layer 2 interface where a Layer 2 input 
filter is applied."

Thanks sounds pretty authoritative.
