Catch up to that fact and revert to their recommended match of BSD-2-Clause.

This is meant to ease those packet manipulation operations such as pushing or popping packet headers, that may be useful to implement software switches, routers and other packet processors. To use the feature, drivers (e.g., iflib, vtnet, etc.) must have explicit support. This change does not add support for any driver, but introduces the necessary kernel changes. However, offsets support is already included for VALE ports and pipes. 2018-12-05T11:57:16Z Vincenzo Maffione vmaffione@FreeBSD.org 2018-12-05T11:57:16Z urn:sha1:b6e66be22bdce2aadcf52ee6230faa1e6cd3f805 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: gnn (mentor) Differential Revision: https://reviews.freebsd.org/D17364
