1016994: Public Summary:
1016994:	The ifpromisc() routine of net/if.c, which handles
1016994:	transitions into and out of promiscuous mode by
1016994:	keeping track of the number of outstanding requests
1016994:	there are for the mode and calling the interface driver
1016994:	to change mode on transitions to and from zero
1016994:	has a bug that causes it to disable promiscuous
1016994:	mode whenever it is called to disable the mode and
1016994:	the number of outstanding requests for the mode is
1016994:	greater than one.
1016994:	The problem occurs only when there are more than one
1016994:	concurrent requesters for promiscuous mode for a
1016994:	particular interface (i.e. run multiple etherfind's
1016994:	on the same interface in parallel, then terminate
1016994:	one of the processes).
1016994: Hook 2:  Needs investigation in release: 4.0.4, 4.0.4c

(There's also a (private | -private) switch.  What does that do?)

1010751: Public Summary:
1010751:	The `IFF_PRIVATE' flag, which can be set by `ifconfig', does not
1010751:	actually do anything.  By design, this flag should prevent the 
1010751:	propagation of routing information associated with the interface

I hope this was informative.
