netmap: refactor logging macros and pipes 2019-02-05T12:10:48+00:00 Vincenzo Maffione vmaffione@FreeBSD.org 2019-02-05T12:10:48+00:00 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.

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.

netmap: align codebase to the current upstream (760279cfb2730a585) 2018-12-05T11:57:16+00:00 Vincenzo Maffione vmaffione@FreeBSD.org 2018-12-05T11:57:16+00:00 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. Sponsored by: Sunny Valley Networks Differential Revision: https://reviews.freebsd.org/D18015
