Currently we have Tx timeout of 50ms while Rx timeout of 20 ms. Tx state machine is maintained by the mailbox framework and Rx by SCPI driver. It is possible that before msg_submit call tx_prepare(because of other message in the queue and the channel being active), wait for completion in scpi_send_message times out and the buffers are freed. In that case when Tx state machine timer goes off later, poll_txdone calls scpi_tx_prepare on that message, which adds it to the rx_pending list, corrupting link pointers. This patch reduces the Tx timeout to 20ms and increases Rx timeout to 30ms to avoid the above mentioned issue.
