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.

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 2018-04-12T07:20:50Z Vincenzo Maffione vmaffione@FreeBSD.org 2018-04-12T07:20:50Z urn:sha1:2ff91c175eca50b7d0d9da6b31eae4109c034137 Changelist: - Turn tx_rings and rx_rings arrays into arrays of pointers to kring structs. This patch includes fixes for ixv, ixl, ix, re, cxgbe, iflib, vtnet and ptnet drivers to cope with the change. - Generalize the nm_config() callback to accept a struct containing many parameters. - Introduce NKR_FAKERING to support buffers sharing (used for netmap pipes) - Improved API for external VALE modules. - Various bug fixes and improvements to the netmap memory allocator, including support for externally (userspace) allocated memory. - Refactoring of netmap pipes: now linked rings share the same netmap buffers, with a separate set of kring pointers (rhead, rcur, rtail). Buffer swapping does not need to happen anymore. - Large refactoring of the control API towards an extensible solution; the goal is to allow the addition of more commands and extension of existing ones (with new options) without the need of hacks or the risk of running out of configuration space. A new NIOCCTRL ioctl has been added to handle all the requests of the new control API, which cover all the functionalities so far supported. The netmap API bumps from 11 to 12 with this patch. Full backward compatibility is provided for the old control command (NIOCREGIF), by means of a new netmap_legacy module. Many parts of the old netmap.h header has now been moved to netmap_legacy.h (included by netmap.h). Approved by: hrs (mentor)
