dpa_offload: Allow 0xff masks for HASH classifier table entries
As key masks are not supported in HASH tables, the DPA Classifier was
refusing to add an entry to a HASH table with a key that had
any mask (mask pointer not NULL). This was changed so that the DPA
Classifier can recognize a 0xff mask all over and ignore it. Any other
(more complex) mask will still be refused.
