Subject: net: ipv4: Set addr_type in hash_keys for forwarded case

From: David Ahern <dsahern@gmail.com>


[ Upstream commit 1fe4b1184c2ae2bfbf9e8b14c9c0c1945c98f205 ]

The result of the skb flow dissect is copied from keys to hash_keys to
ensure only the intended data is hashed. The original L4 hash patch
overlooked setting the addr_type for this case; add it.

Fixes: bf4e0a3db97eb ("net: ipv4: add support for ECMP hash policy choice")
