See details in the log for svn 261909. 2013-05-30T14:07:14Z Luigi Rizzo luigi@FreeBSD.org 2013-05-30T14:07:14Z urn:sha1:f18be5766f1c00051020f9f5b174db57e74f437e - the VALE switch now support up to 254 destinations per switch, unicast or broadcast (multicast goes to all ports). - we can attach hw interfaces and the host stack to a VALE switch, which means we will be able to use it more or less as a native bridge (minor tweaks still necessary). A 'vale-ctl' program is supplied in tools/tools/netmap to attach/detach ports the switch, and list current configuration. - the lookup function in the VALE switch can be reassigned to something else, similar to the pf hooks. This will enable attaching the firewall, or other processing functions (e.g. in-kernel openvswitch) directly on the netmap port. The internal API used by device drivers does not change. Userspace applications should be recompiled because we bump NETMAP_API as we now use some fields in the struct nmreq that were previously ignored -- otherwise, data structures are the same. Manpages will be committed separately. 2013-04-30T16:08:34Z Luigi Rizzo luigi@FreeBSD.org 2013-04-30T16:08:34Z urn:sha1:849bec0e760b99364545f0b4d570ed60767a1475 - netmap_rx_irq()/netmap_tx_irq() can now be called by FreeBSD drivers hiding the logic for handling NIC interrupts in netmap mode. This also simplifies the case of NICs attached to VALE switches. Individual drivers will be updated with separate commits. - use the same refcount() API for FreeBSD and linux - plus some comments, typos and formatting fixes Portions contributed by Michio Honda 2013-04-29T18:00:53Z Luigi Rizzo luigi@FreeBSD.org 2013-04-29T18:00:53Z urn:sha1:d4b42e08696b1dc7089bfd21edd6f0f621f30b0d remove $Id$ lines, and add blank lines around some #if / #elif /#endif 2013-04-19T21:08:21Z Luigi Rizzo luigi@FreeBSD.org 2013-04-19T21:08:21Z urn:sha1:2579e2d715f7a6d1731587402dce0b2c01c9eeea - remove vestiges of the old memory allocator - clean up some comments 2013-01-23T03:51:47Z Luigi Rizzo luigi@FreeBSD.org 2013-01-23T03:51:47Z urn:sha1:ae10d1afee12f511292a6678057afd8708d1c123 add infrastracture to adapt to changes in number of queues and buffers at runtime 2013-01-17T22:14:58Z Luigi Rizzo luigi@FreeBSD.org 2013-01-17T22:14:58Z urn:sha1:1dce924d2528107dd2c49bf68434bca3135b2fbf two upcoming features: semi-transparent mode: when a device is opened in this mode, the user program will be able to mark slots that must be forwarded to the "other" side (i.e. from NIC to host stack, or viceversa), and the forwarding will occur automatically at the next netmap syscall. This saves the need to open another file descriptor and do the forwarding manually. direct-forwarding mode: when operating with a VALE port, the user can specify in the slot the actual destination port, overriding the forwarding decision made by a lookup of the destination MAC. This can be useful to implement packet dispatchers. No API changes will be introduced. No new functionality in this patch yet.
