Re: crc32 cleanups

[Jeff Garzik]

More comments:
* if ether_crc is always == ether_crc_be, then create a #define instead
  of patching driver code
* no need to inline ether_crc_be, stick it in lib/crc32.c also
* using a ref-counting init_crc32 and cleanup_crc32, you do not need
  CONFIG_xxx tests, per driver, in the code itself.  Either make
  lib/crc32 a permanent part of the kernel, or make it a separate module
  which is enabled by makefile rules.  Example:

(linux/lib/Makefile)
obj-$(CONFIG_TULIP) += crc32.o
obj-$(CONFIG_NATSEMI) += crc32.o
obj-$(CONFIG_DMFE) += crc32.o
obj-$(CONFIG_ANOTHERDRIVER) += crc32.o

makefile rules eliminate the duplicates...
