Add hex min and max to match-range-using-tcam #30

Closed hesingh closed 4 years ago

hesingh commented 4 years ago

The current Python code does not accept a hex number for min and max with match-range-using-tcam.

One way to fix the issue is to add this function at the top of the code.

def auto_int(x):
        return int(x, 0)

Then changing type=int to type=auto_int where min and max are parsed.

Then this use of the Python code works.

python range-to-tcam-entries.py --bit-width 16 --min 0x0800 --max 0x0806
