non-raw/header-included sockets, eg BGP tcp sockets, a user like GNU Zebra / Quagga would much prefer packets to be dropped.

Ur... not for TCP.. obviously.

Anyway, is there any advice on how applications that use a single socket for raw/udp should deal with this new behaviour? All of the link-orientated routing protocol daemons in Quagga/GNU Zebra are going to break on Linux with this new behaviour.

Should such applications be changed to open a seperate socket per interface? Or could we have a SO_DROP_DONT_QUEUE sockopt to allow a privileged application to retain the previous behaviour, or some way to flush the queue for a socket?

Using a socket per interface wont address problem of sending quite stale packets when a link comes back after a long time down, AUI. (not a huge problem - but not nice).

Jeff???
