monitor: fix cb restore when monitored adapter unregisters

2022-12-31T12:01:53+00:00

netmap_monitor_stop() called nm_monitor_none() after the head of
the zero-copy monitors had been reset, thus thinking that there
was nothing left to do.

netmap: monitor: add a flag to distinguish packet direction

2021-09-26T14:00:04+00:00

The netmap monitor intercepts any TX/RX packets on the monitored
port. However, before this change there was no way to tell
whether an intercepted packet was being transmitted or received
on the monitored port.
A TXMON flag in the netmap slot has been added for this purpose.

netmap: refactor logging macros and pipes

2019-02-05T12:10:48+00:00

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 (sha 8374e1a7e6941)

2018-10-23T08:55:16+00:00

Changelist:
    - Move large parts of VALE code to a new file and header netmap_bdg.[ch].
      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
