Ensure that bpf_mtap() is always called at the same interrupt priority
level within the tun(4) driver. Otherwise we can be interrupted whilst
copying a packet into the BPF buffer, leading to a race between bpf_mtap()
calls. This can result in corruption within the BPF buffers.
Also ensure that we are at IPL_NET when calling ether_input_mbuf().
Fixes PR6073.
