The Intel Wireless Multicomm 3200 hardware is a combo
card with GPS, Bluetooth, WiMax and 802.11 radios. It
runs over SDIO and is typically found on Moorestown
based platform. This driver takes care of the 802.11
part, which is a fullmac one.
If you choose to build it as a module, it'll be called

*
* The purpose of the sk_has_sleeper and sock_poll_wait is to wrap the memory
* barrier call. They were added due to the race found within the tcp code.
*
* Consider following tcp code paths:
*
* CPU1 CPU2
*
* sys_select receive packet
* ... ...
* __add_wait_queue update tp->rcv_nxt

* ... {
* schedule ...
* if (sk->sk_sleep && waitqueue_active(sk->sk_sleep))
* wake_up_interruptible(sk->sk_sleep)
* ...
* }
*
* The race for tcp fires when the __add_wait_queue changes done by CPU1 stay
* in its cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1
* could then endup calling schedule and sleep forever if there are no more
* data on the socket.
*
* The sk_has_sleeper is always called right after a call to read_lock, so we
* can use smp_mb__after_lock barrier.
