[PATCH] net/openvswitch: replace memcmp() with specialized comparator

Tune flow table lookup in net/openvswitch, replacing a call to the slow-but-safe memcmp() in lib/string.c with a key comparator routine that presumes most comparisons will succeed. Besides avoiding an early-exit test on each iteration, it also compares keys 4 or 8 bytes at a time on architectures
