Change details: - Async mode of Tx/Rx queue initialization in BNAD from a task queue context runs into non-unique taskq allocation issues. Get rid of Tx/Rx initialization from task q context - In the attach function, wait for IOC enable, then do Tx/Rx queue initialization. Default BNA attributes are used when IOC enable from attach fails and values are set to: 1 TxQ, 1 RxQ, 1 Unicast MAC, 1 RIT entry Signed-off-by: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.
