 Hi,
 
 I also encountered this bug, but with UNIX domain sockets and datagrams
 (NetBSD 3.0). It fails when using sendmsg() and using select() does not
 help: it returns that the descriptor is ready but attempting to send
 returns ENOBUFS. This error requires busy-waiting (not very efficient)
 as a work-around when ENOBUFS occurs.
 
 Bug seems to affect datagram services in general and it is probably not
 just IFQ_ENQUEUE because there is no IP or ethernet involved for my
 case.
 
 Hope this helps.
