uip: Move the uip source into a subdirectory.
The network stack code is being refactored so that the IPV6 stack won't
conflict with the IPV4 one, aka uip.

- The link level header length.
-
- This is the offset into the uip_buf where the IP header can be
- found. For Ethernet, this should be set to 14. For SLIP, this
- should be set to 0.
-
- We probably won't use this constant for other link layers than
- ethernet as they have variable header length (this is due to
- variable number and type of address fields and to optional security
- features)
-
- E.g.: 802.15.4 -> 2 + (1/2*4/8) + 0/5/6/10/14
- 802.11 -> 4 + (6*3/4) + 2

+config UIP_BROADCAST
+ bool "Broadcast support"
+ default n
+ help
+ Determines if uIP will pass received broadcast/multicast IPv4 UDP
+ packets to the application (all multicast addresses are treated as
+ broadcast in that case, there is no IGMP support). uIP can always
+ send outgoing broadcast packets regardless of this option.
+
+config UIP_LLH_LEN
+ int "Link level header length"
+ default 14
+ help
+ The link level header length.
+
+ This is the offset into the uip_buf where the IP header can be
+ found. For Ethernet, this should be set to 14. For SLIP, this
+ should be set to 0.
+
+ We probably won't use this constant for other link layers than
+ ethernet as they have variable header length (this is due to
+ variable number and type of address fields and to optional security
+ features)
+
+ E.g.: 802.15.4 -> 2 + (1/2*4/8) + 0/5/6/10/14
+ 802.11 -> 4 + (6*3/4) + 2
