I've cloned the repository, and tried to build examples. The following error appeared:

paskozdilar@workstation:~/stuff/go/packet/examples/arpspoofer$ go build
# github.com/irai/packet/examples/arpspoofer
link: golang.org/x/net/internal/socket: invalid reference to syscall.recvmsg
paskozdilar@workstation:~/stuff/go/packet/examples/arpspoofer$

Researching a bit, I've discovered that Go 1.23 is disallowing some //go:linkname directives that are used in some of the dependencies. Building with the linker flag -checklinkname=0 still works:

paskozdilar@workstation:~/stuff/go/packet/examples/arpspoofer$ go build -ldflags '-checklinkname=0'
paskozdilar@workstation:~/stuff/go/packet/examples/arpspoofer$

After some investigation, the issues seem related to the upgrade of the golang.org/x/net and golang.org/x/sys libraries.
Downgrading them to the version used in [email protected] makes builds work again.

I've created a PR that fixes this: #16
