This reverts commit 0dca2c7404.
The commit in question breaks hardware offload of flower filters.
Quoting Vladimir Oltean <olteanv@gmail.com>:
fl_hw_replace_filter() and fl_reoffload() create a struct
flow_cls_offload with a rule->match.mask member derived from the mask
of the software classifier: &f->mask->key - that same mask that is used
for initializing the flow dissector keys, and the one from which Boris
removed the basic.n_proto member because it was bothering him.
