From: Ratheesh Kannoth <[email protected]>
In the current driver, NPC exact match feature was not getting
enabled as configured bit was not read properly.
for_each_set_bit_from() need end bit as one bit post
position in the bit map to read NPC exact nibble enable
bits properly. This patch fixes the same.
Fixes: b747923afff8 ("octeontx2-af: Exact match support")
