Hi. I've sent this patch for ipset some time ago. It fixes a bug that surfaces itself on some platforms (notably on mips routers running openwrt). Unfortunately I have not seen any feedback/response to this patch. Is something wrong with the proposed fix or with patch itself? Could you please let me know.

Currently it is impossible to set timeout on some architectures (MIPS ar71xx at least) because timeout is parsed into long long data type but used as uint32 without proper conversion.
