1d02345a24 a bit more cleaning of the network header wrappers.
base/inet.hh:
    add functions to the various headers to grab the most common
    encapsulated protocols.  This could easily get out of hand, but
    we're just worrying about tcp, udp, and ip for now.

    add common functions size(), bytes(), and payload() to all wrappers.
    size() gets the header size
    bytes() returns a uint8_t * to the beginning of the header
    payload() returns a uint8_t * to the beginning of the payload.
dev/etherpkt.cc:
dev/etherpkt.hh:
    don't cache pointers to headers.  It's probably not worth the
    hassle.

a58b834c8e Clean up network header stuff and make it more generic. Use
libdnet when we can instead of our own home grown stuff.

SConscript:
    separate the crc code into its own file
base/inet.cc:
    move the crc stuff to crc.cc
    add generic code for calculating ip/tcp/udp checksums
base/inet.hh:
    -  move crc stuff to crc.hh
    -  #include all of the libdnet stuff.  (this makes base/inet.hh the
    only file you need to include if you want to use this kind of stuff.)
    -  Wrap some of the libdnet structs to get easier access to structure
    members.  These wrappers will automatically deal with masking/shifting/
    byte-swapping.
base/refcnt.hh:
    If one derives from RefCountingPtr, they should have access to
    the internal data pointer.
build/SConstruct:
    make #include of dnet stuff work
dev/etherlink.cc:
dev/ethertap.cc:
dev/ethertap.hh:
    EtherPacket -> PacketData
dev/etherpkt.cc:
    EtherPacket -> PacketData
    add a function for populating extra info about a packet.
    Basically just gives pointers to ethernet/ip/tcp/udp headers
    if they exist.
dev/etherpkt.hh:
    EtherPacket -> PacketData
    remove most of the packet header stuff from teh PacketData
    class and just add a few generic functions for grabbing various
    headers that may exist in the packet.  The old functionality is
    contained in the headers.
dev/ns_gige.cc:
    -  IP -> Ip, UDP -> Udp, TCP ->Tcp when used in variable names
    -  get rid of our own byte swapping functions.
    -  whack checksum code and use libdnet version.
    -  Get pointers to the various packet headers and grab info from
    those headers.  (The byte swapping in the headers now.)
    -  Add stats for Udp Checksums
dev/ns_gige.hh:
    use libdnet for checksum code.
    IP -> Ip, TCP -> Tcp in variable names
    add stats for UDP checksums

0b0a6778c9 Fixup interrupting of the ethernet device.
dev/ns_gige.cc:
    clean up the interrupt handling code so that it is simpler and
    less prone to bugs.  I hope I removed the bug where the:
    assert(intrTick >= curTick || intrTick == 0); would get triggered.
    I'm pretty sure that was due to intrTick not being cleared when
    the interrupt was cleared.

    This code probably still needs to be looked at more closely to
    make sure interrupts are not missed.

9023f5c96d - Clean up and factor out all of the binning code into a
single place so it's easier to work with.
-  Add support for binning kernel/user/idle time separately from
lisa's binning stuff, but make the two compatible.
-  KernelStats used to directly implement the pImpl idiom, but
it makes more sense to just remove the level of indirection and
make the exec context have a pointer to the stats.
-  Factor common code out of LinuxSystem and Tru64System and put
it into the System base class.  While doing that, make all
constructors take a pointer to a parameter struct instead of
naming the parameters individually to make it much easier to add
parameters to these classes.

SConscript:
    Move the function tracking and binning stuff around.
arch/alpha/ev5.cc:
    kernelStats is now a pointer
arch/alpha/pseudo_inst.cc:
    kernelStats is now a pointer
    the parameters to the system have been moved into their own
    struct
base/trace.hh:
    provide a little functor class for wrapping a string that
    can allow you to define name() in any scope very simply
    for use with DPRINTF
cpu/base_cpu.cc:
    New order of arguments for consistency.
cpu/exec_context.cc:
    kernelStats no longer has the level of indirection in it,
    execContext has the indirection now.  so, kernelStats is a pointer.
    We also need a pointer to the kernelBinning stuff from the system
    and we need to figure out if we want to do binning or not.
    Move a whole bunch of code into kern_binning.cc so it's all
    in the same place.
cpu/exec_context.hh:
    We want pointers to the kernel binning/stats stuff and we'll
    have the exec_context and system have the level of indirection
    instead of having the extra layer in the kernel stats class.
cpu/simple_cpu/simple_cpu.cc:
    call through the exec context to do the special binning
    stuff.
kern/kernel_stats.cc:
kern/kernel_stats.hh:
    Re-organize the stats stuff and remove the level of indirection
    (that was there to simplify building) and move the binning stuff
    into its own class/file.
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
kern/tru64/tru64_system.cc:
kern/tru64/tru64_system.hh:
sim/system.cc:
sim/system.hh:
    move lots of common system code into the base system class so
    that it can be shared between linux, tru64, and whatever else
    we decide to support in the future.

    Make the constructor take a pointer to a parameter struct so that
    it is easier to pass parameters to the parent.
kern/system_events.cc:
    move the majority of the binning code into the Kernel::Binning class
    in the kern_binning file
kern/system_events.hh:
    FnEvents only need to know the bin
    create the Idle start event to find the PCBB of the idle
    process when it starts.
kern/tru64/tru64_events.cc:

sim/process.cc:
sim/process.hh:

b376c6f420 Added debug printk support
arch/alpha/ev5.hh:
    Added max address PAL code can be at
arch/alpha/vtophys.cc:
    Check max address pal can be at so we don't do the wrong conversion
    if gdb asks for an unaligned access.

a3a1b4dbae better debugging
dev/ns_gige.cc:
    Make all DPRINTF statements take one line. If they need two lines,
    break them up into separate statements.  This makes grep much more
    effective since *every* line will be prefixed by the cycle that the
    trace message is from and the object that caused the message.
    normalize some debugging statements so that searching is easier
    (e.g. always say rxState, not rx state or receive state)
    break into the debugger when a packet is dropped since we don't really
    like dropping packets.

e60a4c58ee Fix a few bugs in the receive state machine. In doing back to tracking
whether or not the state machine is enabled rather than tracking the
specific instance of trying to halt the state machine.

dev/ns_gige.cc:
    change back to tracking the state machine's enableness instead of
    whether or not it is trying to halt.  Also fix a major bug that
    would cause the NIC to drop packets when the rx state machine was
    idle, but enabled.
    Fix a couple other bugs in the state machine where the idle interrupt
    would happen at the wrong time.
    Add a warning to deal with improper values of intrTick
dev/ns_gige.hh:
    We need to keep track of whether the state machine is enabled
    or not separately from the control register since the bits don't
    always reflect the truth.
