Describe the bug

Since updating to version v0.17.2 and higher, I can no longer build the project DNS-collector on FreeBSD. It was OK before 0.17.2

How to reproduce

Try building the project on FreeBSD using the following command:

$ CGO_ENABLED=0 GOOS=freebsd GOARCH=amd64 go build -ldflags="-s -w" -o dnscollector *.go
This results in the following error:

workers/sniffer_xdp.go:77:25: undefined: perf.NewReader
