With CONFIG_NET=n, I get two link errors:

(1) The `dev_ioctl' error is because of the added call in sock_ioctl
    (net/socket.c) to dev_ioctl #ifdefed on WIRELESS_EXT, which is defined
    in <linux/wireless.h>.  Since net/socket.c actually includes
    <linux/wireless.h> twice, once #ifdefed, and once not, I just got rid
    of the non-#ifdefed include, which seems to solve the problem:

(2) `__secpath_destroy' is used by the inline function `secpath_put',
    in <net/xfrm.h>, and net/core/skbuff.c calls secpath_put -- but
    __secpath_destroy is defined in net/ipv4/xfrm_input.c, and the
    net/ipv4 directory isn't even compiled if CONFIG_NET=n.
    [I didn't know what to do about this, so I just commented out the call
    to __secpath_destroy in secpath_put]
