A similar message is printed elsewhere as a result of if_link_state_change(). c162511 Explicity compare pointer to NULL c162510 Allocate the mac filter table at attach time. c162509 Add real BSD licenses to the header files copied from Linux. The chases upstream changes made in Linux awhile ago. c162508 Only notify if we actually dequeued something. c162507 Change a couple of if () { KASSERT(...) } to just KASSERTs. In non-debug kernels, the if() { } probably get optomized away, but I guess this is clearer. c162506 Remove VIRTIO_BLK_F_TOPOLOGY fields in the config. TOPOLOGY has since been removed from the spec, and the FreeBSD didn't really do anything with the fields anyways. c162505 Move vtblk_enqueue_request() outside the locks when getting the ident. c162504 Remove soon to be uneeded trylock during dump [1]. http://lists.freebsd.org/pipermail/freebsd-current/2011-November/029226.html c162503 Remove emtpy line c162502 Drop frame if cannot allocate a vtnet_tx_header. If we don't, we set OACTIVE, but if there are no other frames in flight, vtnet_txeof() will never be called to unset OACTIVE. The interface would have to be down/up'ed in order to become usable. We could be cuter here and only do this if the virtqueue is emtpy, but its probably not worth the complication. c162501 Start mbuf replacement loop at 1 for clarity Obtained from: Bryan Venteicher bryanv at daemoninthecloset dot org
