netmap: upgrade sync-kloop support2019-02-02T22:39:29ZVincenzo Maffionevmaffione@FreeBSD.org2019-02-02T22:39:29Zurn:sha1:5faab7782202ab1e6815c5da956d8997f59aa105
Add SYNC_KLOOP_MODE option, and add support for direct mode, where application
executes the TXSYNC and RXSYNC in the context of the ioeventfd wake up callback.

netmap: add notifications on kloop stop2019-01-29T10:28:50ZVincenzo Maffionevmaffione@FreeBSD.org2019-01-29T10:28:50Zurn:sha1:a56136a1ba97e9b7cbe914f5d9549c852620640e
On sync-kloop stop, send a wake-up signal to the kloop, so that
waiting for the timeout is not needed.
Also, improve logging in netmap_freebsd.c.

netmap: improvements to the netmap kloop (CSB mode)2019-01-23T14:51:36ZVincenzo Maffionevmaffione@FreeBSD.org2019-01-23T14:51:36Zurn:sha1:f79ba6d75befff748df583a570e368c8f3434dc7
Changelist:
- Add the proper memory barriers in the kloop ring processing
functions.
- Fix memory barriers usage in the user helpers (nm_sync_kloop_appl_write,
nm_sync_kloop_appl_read).
- Fix nm_kr_txempty() helper to look at rhead rather than rcur. This
is important since the kloop can read a value of rcur which is ahead
of the value of rhead (see explanation in nm_sync_kloop_appl_write)
- Remove obsolete ptnetmap_guest_write_kring_csb() and
ptnet_guest_read_kring_csb(), and update if_ptnet(4) to use those.
- Prepare in advance the arguments for netmap_sync_kloop_[tr]x_ring(),
to make the kloop faster.
- Provide kernel and user implementation for nm_ldld_barrier() and
nm_ldst_barrier()
