domcyrus · domcyrus · commit 972d4de2f4cf · 2025-11-22T18:07:36.000+01:00
- Made libbpf-cargo an optional build dependency
- Only builds when ebpf feature is enabled
- Added Cross.toml configuration for FreeBSD to install libpcap
- Verified libbpf-sys no longer tries to build for FreeBSD
- Now fixing linker error for missing libpcap
