Florent Kermarrec 7a988bee22 core: Add initial/minimal DHCP support to hardware stack. 
Ex of use in a  SoC that issues a DHCP request per second:

# Signals.
ip_address  = Signal(32)
mac_address = Signal(48, reset=0x10e2d5000001)

# Request Timer.
self.dhcp_timer = dhcp_timer = WaitTimer(int(sys_clk_freq/2))
self.comb += self.dhcp_timer.wait.eq(~self.dhcp_timer.done)

# DHCP.
dhcp_port = self.ethcore_etherbone.udp.crossbar.get_port(68, dw=32, cd="sys")
self.dhcp = dhcp = LiteEthDHCP(udp_port=dhcp_port, sys_clk_freq=sys_clk_freq)
self.comb += [
    dhcp.start.eq(self.dhcp_timer.done),
