New Revision: 205904
URL: http://svn.freebsd.org/changeset/base/205904
Log:
Thanks to Michael Tuexen for adding SCTP support for 82599,
also for finding a one character bug that kept TSO from working.
Sometimes with direct attach cables a failure can occur in init,
the old method of calling detach was broken, there is no way to
return an error to the system from init, so I have changed it to
return failure thru the ioctl.
And, have fixed the ALTQ code changes of Max Laier, sorry Max :)
