feedback from John Linville to move this to lib directory, the linux
source has been searched. Although there is currently only one other
kernel driver using this algorithm (ie. drivers/ssb) we are providing
this as a library function for others to use.
that are different - eg bit direction and it's going to be confusing to
just call it 'crc8'
No problem. I just had a look at the lib directory and noticed the crc7
function and module is called crc7. I can imagine there are enough
variants of that as well. Another variation is probably the polynomial
used. Not sure how to factor in bit direction and polynomial into the name.
suggestions from my thumb:
- rnw_crc8: refers to Ross N. Williams who wrote the paper used for
implementing this function.
- painless_crc8: refers to title of the paper "A Painless Guide to CRC
Error Detection Algorithms".
- brcm_crc8: indicates where the function came from.
Other suggestions are welcome.
Almost nobody dances sober, unless they happen to be insane.
