dhcp: Reduce socket creation/bind latency When creating a PF_PACKET socket with subsequent bind() call - both using the same protocol argument - passing the protocol to socket() is redundant and omitting it can save some latency. This should drop the cost of the subsequent bind() to almost zero, see [1] for details.
