I think you found the problem.
Reading again my description, I realize it's biased toward the result I needed
from the data I had to analyze.
Which is:
- bit fields smaller than a byte
- 2-bytes words in LE byte ordering
- each byte using BE bit ordering
So I needed to find a way to extract, say, 0x3 from {0x80, 0x1}, given offset =
7 bits and length = 2 bits.
Maybe this won't fit in just one function, and byte ordering should be "fixed"
independently of bit field extraction...
