the following patch
diff --git a/drivers/net/wireless/ti/wl1251/rx.c
b/drivers/net/wireless/ti/wl1251/rx.c
index 123c4bb..cde0eaf 100644

@@ -180,7 +180,7 @@ static void wl1251_rx_body(struct wl1251 *wl,
wl1251_mem_read(wl, rx_packet_ring_addr, rx_buffer, length);
/* The actual length doesn't include the target's alignment */
- skb->len = desc->length - PLCP_HEADER_LENGTH;
+ skb_trim(skb, desc->length - PLCP_HEADER_LENGTH);
fc = (u16 *)skb->data;
seems to fix the issue, including those "corrupt probe response"
messages in dmesg log (I took that 'skb_trim' from the original Nokia
kernel). Will send a properly formatted patch shortly.
Thanks,
Ivo
