Re: [Freeipmi-devel] ipmi_lan_open_session() question

Jim,

I forgot to ask.  What motherboard are you attempting to work with? 
I've fixed a number of session startup corner cases in 'ipmipower' that
aren't in libfreeipmi.  Some motherboards flat out handle sequence
numbers wrong and I (make a reasonable attempt to) work around it in
ipmipower.
