sg	c6b742812d	fixed bug #38203: DHCP options are not recorded in all DHCP ack messages (patch by Florent Matignon)	2016-03-23 21:06:52 +01:00
Dirk Ziegelmeier	6aed6e659f	Rework DHCP PCB handling: Old code registered one UDP PCB per netif where DHCP was active and there was a special case in udp_input() for this. New implementation uses one PCB for all netifs and removes special case in udp_input(). ... The old approach called udp_bind() on each of the PCBs, which puts them into udp_pcbs list. The PCBs were iterated on all non-DHCP udp_inputs() with no effect. My cleanup removes the special handling in udp.c, and uses only one DHCP UDP PCB to catch all DHCP messages from all netifs. The dhcp_recv function then checks whether ip_current_input_netif() has DHCP enabled - if not, the message is ignored. The PCB is only created/registered when one or more PCBs have DHCP enabled.	2016-02-29 19:31:19 +01:00
