netmap: add support for multiple host rings

2019-03-18T12:22:23Z

Some applications forward from/to host rings most or all the traffic received or sent on a physical interface. In this cases it is desirable to have more than a pair of RX/TX host rings, and use multiple threads to speed up forwarding. This change adds support for multiple host rings. On registering a netmap port, the user can specify the number of desired receive and transmit host rings in the nr_host_tx_rings and nr_host_rx_rings fields of the nmreq_register structure.

netmap: refactor logging macros and pipes

2019-02-05T12:10:48Z

Changelist: - Replace ND, D and RD macros with nm_prdis, nm_prinf, nm_prerr and nm_prlim, to avoid possible naming conflicts. - Add netmap_krings_mode_commit() helper function and use that to reduce code duplication. - Refactor pipes control code to export some functions that can be reused by the veth driver (on Linux) and epair(4). - Add check to reject API requests with version less than 11. - Small code refactoring for the null adapter. MFC after: 1 week

netmap: align codebase to the current upstream (760279cfb2730a585)

2018-12-05T11:57:16Z

Changelist: - Replace netmap passthrough host support with a more general mechanism to call TXSYNC/RXSYNC from an in-kernel event-loop. No kernel threads are used to use this feature: the application is required to spawn a thread (or a process) and issue a SYNC_KLOOP_START (NIOCCTRL) command in the thread body. The kernel loop is executed by the ioctl implementation, which returns to userspace only when a different thread calls SYNC_KLOOP_STOP or the netmap file descriptor is closed. - Update the if_ptnet driver to cope with the new data structures, and prune all the obsolete ptnetmap code. - Add support for "null" netmap ports, useful to allocate netmap_if, netmap_ring and netmap buffers to be used by specialized applications (e.g. hypervisors). TXSYNC/RXSYNC on these ports have no effect. - Various fixes and code refactoring. Sponsored by: Sunny Valley Networks Differential Revision: https://reviews.freebsd.org/D18015

netmap: align codebase to the current upstream (sha 8374e1a7e6941)

2018-10-23T08:55:16Z

Changelist: - Move large parts of VALE code to a new file and header netmap_bdg.[ch]. This is useful to reuse the code within upcoming projects. - Improvements and bug fixes to pipes and monitors. - Introduce nm_os_onattach(), nm_os_onenter() and nm_os_onexit() to handle differences between FreeBSD and Linux. - Introduce some new helper functions to handle more host rings and fake rings (netmap_all_rings(), netmap_real_rings(), ...) - Added new sysctl to enable/disable hw checksum in emulated netmap mode. - nm_inject: add support for NS_MOREFRAG Approved by: gnn (mentor) Differential Revision: https://reviews.freebsd.org/D17364
