wpa_supplicant requires support for packet sockets. It sounds like your
kernel does not include this in its configuration.

Reconfigure and build the kernel with CONFIG_PACKET included.

Unlikely. I would assume that they use packet sockets on Linux..

Please also note that with most drivers, you need to have at least Linux
wireless extensions version 15 and that was added in Linux 2.4.21, so
you would need to either upgrade your kernel or at least include the
patch for newer wireless extensions version.
