a109296bde Fix a bug where we would improperly calculate if the FIFO was
full by adding a reserve feature to the packet fifo which allows
us to reserve space in the fifo if only part of a packet was
copied into the fifo.

dev/ns_gige.cc:
    use the new reserve feature in the fifo to properly determine
    when we're full.  assert that adding a packet to the fifo suceeds.
dev/pktfifo.hh:
    add the ability to reserve space in the fifo.  This is useful for
    partial writing of packets into the fifo.

b031888038 Use parameter structs for initialization so it's easier

it is unnecessary to know know platform specifics for
interrupting or translating PCI DMA addresses.

    dma addresses
dev/platform.cc:
    have default functions that panic on pci calls
dev/platform.hh:
    don't make the pci stuff pure virtual, but rather provide
    default implementations that panic.  Also, add dma address
    translation.

b881408ed7 Clean up the Range class and associated usages. The code was
never clear about whether the end of the range was inclusive
or exclusive.  Make it inclusive, but also provide a RangeSize()
function that will generate a Range based on a start and a size.
This, in combination with using the comparison operators, makes
almost all usages of the range not care how it is stored.

base/range.cc:
    Make the end of the range inclusive.

    start/end -> first/last
    (end seems too much like end() in stl)
base/range.hh:
    Make the end of the range inclusive.

    Fix all comparison operators so that they work correctly with
    an inclusive range.  Also, when comparing one range to another
    with <, <=, >, >=, we only look at the beginning of the range
    beacuse x <= y should be the same as x < y || x == y.  (This wasn't
    the case before.)

    Add a few functions for making a range:
    RangeSize is start and size
    RangeEx is start and end where end is exclusive
    RangeIn is start and end where end is inclusive

    start/end -> first/last
    (end seems too much like end() in stl)

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.

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.

    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

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.

    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.

    make tx/rx fifo sizes a param. the default is 128K for each.  also, make the state machine not move onto txFragRead if there is no room in the txfifo for data.

4f4252fa89 Remove second pciToDma translation on current PRD address pointer b/c
second translation (which is superfluous) doesn't work properly when
system memory is higher than 128MB

7b2691d537 when you add caches, dma commands within the state machine are delayed and cause the state machine to exit until the dma comes back. thus, all relevant code must be executed BEFORE going to do the dma code.
dev/ns_gige.cc:
    rearrange code so nothing gets skipped when "doing dma."

19fd3439c7 tag each mem_req as coming from the nic if it is DMA'd from the NIC. the NIC tells the DMA interface, which in turn sets a new nic_req flag in the MemReq it makes.
dev/ns_gige.cc:
    tell all outgoing dma events that this request is from the NIC

    transmit side checksum offloading doesn't need pseudo header generation, it just takes the pseudo header checksum and uses it.

Both rx/tx interrupts are now scheduled for the future to give the
linux kernel time to get out of its loop.
