++	----------	------------------------------------------------
++	10-07-2007	Clean up the driver using checkpatch
++	08-24-2006	Support at linux 2.6.10 above
++	03-24-2006	Support NAPI
++	03-21-2006	By Charies,change spin_lock_irqsave(lp->lock, flags) 
++			to spin_lock_irqsave(&lp->lock, flags)
++			in set_multicast_list
++	03-15-2006      Modify the set_multicast_list ,due to when re-plug the ethernet,
++			it will forget the previous setting
++	07-12-2005	Tim, modify the set_multicast_list
++	03-28-2005	Tim, modify some error mac register offset in 
++			function set_multicast_list
++	03-27-2005	Tim, Add the internal state machine reset
++			Sten, If multicast address more than 4, enter PROM mode
++			Changed rdc to r6040
++	12-22-2004	Sten Init MAC MBCR register=0x012A
++			PHY_CAP = 0x01E1
++
++	Need to Do LIst:
++	1. If multicast address more than 4, use the multicast address hash

++ * Getting to provable safe in place decompression is hard.
++ * Worst case behaviours need to be analized.
++ * Background information:
++ *
++ * The file layout is:
++ *    magic[2]
++ *    method[1]
++ *    flags[1]
++ *    timestamp[4]
++ *    extraflags[1]
++ *    os[1]
++ *    compressed data blocks[N]
++ *    crc[4] orig_len[4]
++ *
++ * resulting in 18 bytes of non compressed data overhead.
++ *
++ * Files divided into blocks
++ * 1 bit (last block flag)
++ * 2 bits (block type)
++ *
++ * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
++ * The smallest block type encoding is always used.
++ *
++ * stored:
++ *    32 bits length in bytes.
++ *
++ * fixed:
++ *    magic fixed tree.
++ *    symbols.
++ *
++ * dynamic:
++ *    dynamic tree encoding.
++ *    symbols.
++ *
++ *
++ * The buffer for decompression in place is the length of the
++ * uncompressed data, plus a small amount extra to keep the algorithm safe.
++ * The compressed data is placed at the end of the buffer.  The output
++ * pointer is placed at the start of the buffer and the input pointer
++ * is placed where the compressed data starts.  Problems will occur
++ * when the output pointer overruns the input pointer.
++ *
++ * The output pointer can only overrun the input pointer if the input
++ * pointer is moving faster than the output pointer.  A condition only
++ * triggered by data whose compressed form is larger than the uncompressed
++ * form.
++ *
++ * The worst case at the block level is a growth of the compressed data
++ * of 5 bytes per 32767 bytes.
++ *
++ * The worst case internal to a compressed block is very hard to figure.
++ * The worst case can at least be boundined by having one bit that represents
++ * 32764 bytes and then all of the rest of the bytes representing the very
++ * very last byte.
++ *
++ * All of which is enough to compute an amount of extra data that is required
++ * to be safe.  To avoid problems at the block level allocating 5 extra bytes
++ * per 32767 bytes of data is sufficient.  To avoind problems internal to a block
++ * adding an extra 32767 bytes (the worst case uncompressed block size) is
++ * sufficient, to ensure that in the worst case the decompressed data for
++ * block will stop the byte before the compressed data for a block begins.
++ * To avoid problems with the compressed data's meta information an extra 18
++ * bytes are needed.  Leading to the formula:
++ *
++ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
++ *
++ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
++ * Adding 32768 instead of 32767 just makes for round numbers.
++ * Adding the decompressor_size is necessary as it musht live after all
++ * of the data as well.  Last I measured the decompressor is about 14K.
++ * 10K of actuall data and 4K of bss.
