From: Tony Krowiak <akrowiak@xxxxxxxxxxxxx> A new APQSW response code (0xA) indicating the designated queue is in the process of being bound or associated to a configuration may be returned from the PQAP(ZAPQ) command. This patch introduces code that will verify when the PQAP(ZAPQ) command can be re-issued after receiving response code 0xA. Signed-off-by: Tony Krowiak <akrowiak@xxxxxxxxxxxxx> Reviewed-by: Jason J.
