[PATCH for-2.6.35] virtio_net: do not reschedule rx refill forever
We currently fill all of RX ring, then add_buf returns ENOSPC, which gets mis-detected as an out of memory condition and causes us to reschedule the work, and so on forever.

[PATCH 3/3] Staging: rtl8192e: Do not send NULL BSSID events when not associated
If we're not associated, we should not send wireless events to let userspace know that we just left an ESSID, simply because we havent yet joined it. If we keep on doing that, wpa_supplicant could receive such events while actually trying to join an ESSID, and thus decide to stop trying. This leads to a lot of conn... 10 Jun 2010 11:08

[PATCH 2/3] Staging: rtl8192e: Do not autoconnect based on probe response
Getting a probe response after sending a probe request to a specific SSID doesnt mean we're trying to associate with this SSID. wpa_supplicant should be the only one deciding when to join an SSID, not the kernel.
