Hi Andi,

OK.  So, _which_ set of netlink functions should I use?
Is rtnl_notify() the correct one to use to send a netlink
request for the RTM_GETQDISC or RTM_GETTCCLASS data?

What's the mechanism used to send and then receive a reply?
Will it be async?  How do I specify the call-back to receive
the reply netlink message?  Or will it be synchronous and
I pass in some call-back-reply function?

Thanks for you suggestions!
jdl
