From: Dmitry Bogdanov <dbogdanov@marvell.com>
commit a42e6aee7f47a8a68d09923c720fc8f605a04207 upstream.
This patch fixes ip dst and ipv6 address filters. There were 2 mistakes in the code, which led to the issue: * invalid register was used for ipv4 dst address; * incorrect write order of dwords for ipv6 addresses.
