This happens because for processing power save sleep confirm command we pull skb so that skb->data points ahead of interface header. We use same skb to get other cmda responses as well. So if we don't push skb after processing cmd response, it results into reduction in skb->len and finally skb->len reaches zero. This causes failure in processing sleep command response. Fix this by pushing skb by INTF_HEADER_LEN at the end of command response processing. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
