List below:
tests.c - implemented "ASSERT" macro, improved "RETURN_IF_FAIL" macro
dm_frame_parser - changed parameter in signature from "char*" to
"uint8_t*"
dm_list - disabled static list allocation - doesn't work in current
implementation
dm_types.h - added "ARP_REPLY" and "ARP_REQUEST" macros for the ARP
frame opcode values
dm_api.c - global variables SHOULD BE STATIC + cosmetic changes
dm_policy_ip_addr_collision - lot of stuff implement, including the most
important log function (still minor TODO's required to be done)
