Current defaults is 8.

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. 2020-06-03T05:49:19Z Vincenzo Maffione vmaffione@FreeBSD.org 2020-06-03T05:49:19Z urn:sha1:06f6997eb5fd0d91560b9eec0f842214c21856e8 MFC after: 1 week 2019-02-05T12:10:48Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-02-05T12:10:48Z urn:sha1:75f4f3ed51ea3eb78ed77e255845aa301b657bc4 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.

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
