libnetmap: add support for the offset features2021-03-29T16:38:37ZVincenzo Maffionevmaffione@FreeBSD.org2021-03-29T16:38:37Zurn:sha1:f8113f0a65ada9367bcbfa6e0d5d8a8451dd8ac2
The companion libnetmap changes for the "offsets" kernel support added
in a6d768d845c173823785c. This includes code to parse the "@offset=NNN"
option that can be appended to the port name by any nmport_* application.
Example:
# pkt-gen -i 'netmap:em0@offset=16'
libnetmap: fix cast from uint64_t to void*2020-09-22T20:20:43ZVincenzo Maffionevmaffione@FreeBSD.org2020-09-22T20:20:43Zurn:sha1:92c5d82c86f1fde4462e7a37238c13e227eabec5
We use uintptr_t as an intermediate cast to avoid compiler
warnings on 32 bit architectures.

lib: add libnetmap2020-08-28T20:03:54ZVincenzo Maffionevmaffione@FreeBSD.org2020-08-28T20:03:54Zurn:sha1:5c4f8d801ca081e38ca3bfd9d36bfcd55329d703
This changeset introduces the new libnetmap library for writing
netmap applications.
Before libnetmap, applications could either use the kernel API
directly (e.g. NIOCREGIF/NIOCCTRL) or the simple header-only-library
netmap_user.h (e.g. nm_open(), nm_close(), nm_mmap() etc.)
The new library offers more functionalities than netmap_user.h:
- Support for complex netmap options, such as external memory
allocators or per-buffer offsets. This opens the way to future
extensions.
- More flexibility in the netmap port bind options, such as
non-numeric names for pipes, or the ability to specify the netmap
allocator that must be used for a given port.
- Automatic tracking of the netmap memory regions in use across the
open ports.
At the moment there is no man page, but the libnetmap.h header file
has in-depth documentation.
