See the feature description in patch #2.
Version 4:
- Fixed image builds with libvirt-ci by adding a new commit that
bumps a submodule version and then using that new version for
libxdp support in the main qemu build.
Based on discussion in the PULL request:
https://lists.gnu.org/archive/html/qemu-devel/2023-09/msg01730.html
Version 3:
- Bump requirements to libxdp 1.4.0+. Having that, removed all
the conditional compilation parts, since all the needed APIs
are available in this version of libxdp.
- Also removed the ability to pass xsks map fd, since ability
to just pass socket fds is now always available and it doesn't
require any capabilities untile manipulations with BPF maps.
- Updated documentation to not call out specific vendors, memory
numbers or specific required capabilities.
- Changed logic of returning peeked at but unused descriptors.
- Minor cleanups.
Version 2:
- Added support for running with no capabilities by passing
pre-created AF_XDP socket file descriptors via 'sock-fds' option.
Conditionally complied because requires unreleased libxdp 1.4.0.
The last restriction is having 32 MB of RLIMIT_MEMLOCK per queue.
- Refined and extended documentation.
