Multicast (again)

[Phil Meyer]

My l33t google skillz have been humbled, even humiliated on this issue.

Recently I asked this group for help with a multicast issue and did not 
get any responses.  That is not unusual for me.  Even in the distant 
past of usenet  my obfuscated postings would win awards (of silence).  
So no criticism is implied or intended.

Might I ask instead how to contact the Fedora kernel developers?  The 
Redhat/Fedora Listman does not feature an internals mailing list (that 
my mind can notice), and my rarity of difficult questions is unworthy of 
attempting to penetrate the lkml.

As a reminder:

It appears that only one interface at a time in a Fedora kernel can send 
multicast packets.  Any documentation as to how to set which interface 
to do it eludes me.

A system with two interfaces (all of our tests featured a wireless 
interface as the second interface) will send multicast packets by 
default over the primary ethernet interface and never over the wireless 
interface.

Thanks for any assistance!
