Cannot build under FreeBSD

[iron-udjin]

OS: FreeBSD 14.2-RELEASE

The frontend builds fine. Trying to build binary:

$ make build
cp scripts/wg-portal.service dist
CGO_ENABLED=1 go build -o dist/wg-portal  -ldflags "-w -s -extldflags \"-static\" -X 'github.com/h44z/wg-portal/internal/server.Version=-'"  -tags netgo  cmd/wg-portal/main.go
# github.com/h44z/wg-portal/internal/lowlevel
internal/lowlevel/netlink.go:57:50: undefined: netlink.FAMILY_V4
internal/lowlevel/netlink.go:62:50: undefined: netlink.FAMILY_V6
internal/lowlevel/netlink.go:99:17: undefined: netlink.RuleAdd
internal/lowlevel/netlink.go:103:17: undefined: netlink.RuleDel
internal/lowlevel/netlink.go:107:17: undefined: netlink.RuleList
*** Error code 1

Firstly I thought the issue was in wgctrl-go but it's not. Pleas check this discussion: WireGuard/wgctrl-go#148

Thank you.
