after merge from head. Checkpointing may need some work now. Endian-happiness still not complete.
SConscript:
add all devices back into make file
base/inet.hh:
dev/etherbus.cc:
dev/etherbus.hh:
dev/etherdump.cc:
dev/etherdump.hh:
dev/etherint.hh:

dev/etherlink.hh:
dev/etherpkt.cc:
dev/etherpkt.hh:
dev/ethertap.cc:
dev/ethertap.hh:
dev/pktfifo.cc:
dev/pktfifo.hh:
rename PacketPtr EthPacketPtr so it doesn't conflict with the PacketPtr type in the memory system
configs/test/fs.py:
add nics to fs.py
cpu/cpu_exec_context.cc:
remove this check, as it's not valid. We may want to add something else back in to make sure that no one can delete the
static virtual ports in the exec context
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
dev/alpha_console.cc:
dev/ide_ctrl.cc:
use new methods for accessing packet data
dev/ide_disk.cc:
add some more dprintfs
dev/io_device.cc:
delete packets when we are done with them. Update for new packet methods to access data
dev/isa_fake.cc:
dev/pciconfigall.cc:
dev/tsunami_cchip.cc:
dev/tsunami_io.cc:
dev/tsunami_pchip.cc:
dev/uart8250.cc:
dev/uart8250.hh:
mem/physical.cc:
mem/port.cc:
dUpdate for new packet methods to access data
dev/ns_gige.cc:
Update for new memory system
dev/ns_gige.hh:
python/m5/objects/Ethernet.py:
update for new memory system
dev/sinic.cc:
dev/sinic.hh:
Update for new memory system. Untested as need to merge in head because of kernel driver differences between versions
mem/packet.hh:
Add methods to access data instead of accessing it directly.
