[dpdk-dev] table: fix table_array for incomplete bitmask
Commit Message
When a lookup was done on a table_array structure with an incomplete
bitmask, the results was always zero hits. This was because the
pkts_mask value was cleared as we process each entry, and the result
was assigned at the end of the loop, when pkts_mask was zero.
Changing the assignment to occur at the start, before the pkts_mask
gets cleared, fixes this issue.
