Add an extra (void *) cast. The struct if_msghdr has an 8 byte
alignment requirement, while rt_msghdr has a 4 byte alignment requirement. The root cause is that if_msghdr has an struct if_data which has an 8-byte alignment requirement due to a time_t that's embedded in it. On MIPS, time_t is a 64-bit number, so must be 64-bit aligned. Since we don't access ifm_data.ifi_epoch, a simple cast is all that's necessary here. It is likely the case that ifi_epoch should *NOT* be a time_t because it is an uptime (time delta) an not an absolute time since 1970. u_long is likely sufficient there since that gives an uptime of 136 years will suffice for the foreseeable future.
