* net/send.c -- Check if the destination IP address is in the ARP table. If
not, then don't consider the packet sent. It won't be, an ARP packet will go
out instead.
* arch/arm/src/lpc17xx/lpc17_emacram.h and lpc17_allocateheap.c -- The Ethernet
logic was using all of AHB SRAM Bank0 for Ethernet packet buffers (16Kb). An
option was added to limit the amount of SRAM used for packet buffering and to
re-use any extra Bank0 memory for heap. configs/olimex-lpc1766stk/nettest
now uses only 8Kb at the beginning of Bank0; the 8Kb at the end of Bank0 is
included in the heap
