if_vtnet: Add initial modern (V1) support Very basic support to get packets flowing on modern QEMU but still several conformance issues remain that will be addressed in later commits. First of many passes at cleaning up various accumulated cruft Reviewed by: grehan (mentor) Differential Revision: https://reviews.freebsd.org/D27904

tap: add support for virtio-net offloads This patch is part of an effort to make bhyve networking (in particular TCP) faster. The key strategy to enhance TCP throughput is to let the whole packet datapath work with TSO/LRO packets (up to 64KB each), so that the per-packet overhead is amortized over a large number of bytes. This capability is supported in the guest by means of the vtnet(4) driver, which is able to handle TSO/LRO packets leveraging the virtio-net header (see struct virtio_net_hdr and struct virtio_net_hdr_mrg_rxbuf). A bhyve VM exchanges packets with the host through a network backend, which can be vale(4) or if_tap(4). While vale(4) supports TSO/LRO packets, if_tap(4) does not. This patch extends if_tap(4) with the ability to understand the virtio-net header, so that a tapX interface can process TSO/LRO packets. A couple of ioctl commands have been added to configure and probe the virtio-net header. Once the virtio-net header is set, the tapX interface acquires all the IFCAP capabilities necessary for TSO/LRO. Reviewed by: kevans Differential Revision: https://reviews.freebsd.org/D21263

sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Do not include <sys/types.h> in the local headers. The .c files including them have already included <sys/param.h> before these headers are included.

Catch up with Bryan Venteicher's virtio Hg repo: c162516 Remove vtblk_sector_size c162515 Wrap long license lines c162514 Remove vtblk_unit c162513 Wrap long lines in the license. c162512 Remove verbose messages when link goes up/down. 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
