[LARTC] NETLINK option is gone in Kernel v2.4.20 configuration?

["Cheng Zhang" <czhang@xxxxxxxxxxxxx>]

Could someone give me a hint? I can't find options in 2.4.20 to enable
CONFIG_NETLINK and CONFIG_RTNETLINK by doing 'make menuconfig'. The only
thing related is CONFIG_NETLINK_DEV (Netlink device emulation).
I pull down 2.4.10, they are there.
