ipv4: Initialize flowi4_multipath_hash in data path
[ Upstream commit 1869e22 ] flowi4_multipath_hash was added by the commit referenced below for tunnels. Unfortunately, the patch did not initialize the new field for several fast path lookups that do not initialize the entire flow struct to 0. Fix those locations. Currently, flowi4_multipath_hash is random garbage and affects the hash value computed by fib_multipath_hash for multipath selection. Fixes: 24ba144 ("route: Add multipath_hash in flowi_common to make user-define hash") Signed-off-by: David Ahern <dsahern@gmail.com> Cc: wenxu <wenxu@ucloud.cn> Signed-off-by: David S.
