Subject: [PATCH net-next 2/7] ipv4: nexthop: Use nla_put_be32() for NHA_GATEWAY

From: Ido Schimmel <>

The code correctly uses nla_get_be32() to get the payload of the
attribute, but incorrectly uses nla_put_u32() to add the attribute to
the payload. This results in the following warning:

net/ipv4/nexthop.c:279:59: warning: incorrect type in argument 3 (different base types)
net/ipv4/nexthop.c:279:59:    expected unsigned int [usertype] value
net/ipv4/nexthop.c:279:59:    got restricted __be32 [usertype] ipv4

Suppress the warning by using nla_put_be32().
