Hi,
        The first two patches are a fix to fix a potential crash with
host_net_remove while doing heavy network I/O.

        The rest of the patches add support for using the new
TUNSETSNDBUF ioctl in 2.6.30 in order to provide some pushback against
UDP applications in the guest who are sending packets faster than the
host can handle them. More detail in the 06/08 patch.

Cheers,
Mark.
