hi,

as per frederic's request, some mld testing...
as that fancy android app does not accept hex characters,
i used my plain old vlc on my ideapad to join the stream:

mc36@ideapad:~$ vlc -I dummy --audio --no-video --aout alsa
rtp://[ff09::1234]/

then the uplink got the mld join request and sent it via pim over bier to
have the info at the sender:

as expected, it arrived on my notebook and set up the bier encap as
expected...

hi,
please find attached the screenshot of my android10 with mcast tester app
gotting the packets of my notebook.
the phone joined with igmp itself! my notebook also notified by igmp, in
between them, the signaling info was
sent through in pim encapped in bier as per the draft, sent through my bier
core with the tofino in the middle...
i have 2 streams on my notebook, one for the phone testing, and the other is
a constant stream to my amplifiers
in 2 rooms.... so android also have built in support, which is good to know!
