Hi Matt,

Definitely open to patches.  Looking over the IPMI spec, I agree w/
A.B., it seems to be more useful for a higher level monitoring, w/ the
Get Message Flags and similar commands.  I can think of several patch

1) add a KCS driver flag for checking for SMS_ATN in addition to OBF (or
instead of??).  Flags may be propogated up into higher level APIs too.

2) an additional function that checks for SMS_ATN in addition/or instead
of OBF that users can call instead.

It would be useful to understand your use case too.  Are you using the
KCS driver and IPMI bridging commands to bridge from one BMC to another
