Add it to the system commands so that it can be used right away. This program was previously called vale-ctl, and stored in tools/tools/netmap Reviewed by: hrs, bcr, lwhsu, kevans Differential Revision: https://reviews.freebsd.org/D22146 2019-02-12T09:07:46Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-02-12T09:07:46Z urn:sha1:01e8e2c2d6d31a2e328e090ab1feda3a68c0d094 netmap: refactor logging macros and pipes 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. 2019-02-06T09:59:20Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-02-06T09:59:20Z urn:sha1:e2e0ef76356f07d4b477b30a87697134b8ad0fd1 netmap: add notifications on kloop stop 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. 2018-12-11T11:31:13Z Vincenzo Maffione vmaffione@FreeBSD.org 2018-12-11T11:31:13Z urn:sha1:b321acab165f6ab6e821be03895eb40e5bff6fe7 netmap: align codebase to the current upstream (760279cfb2730a585) 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.

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: re (gjb)
