Various patches have ended up changing the style of the symbolic macros/register defines to different style. As a result, the current kernel.org files are a mix of different macro styles. Since this macro/register defines is used by different drivers a few patch series have ended up adding duplicate macro/register define entries with different styles. This makes these register define/macro files a complete mess and we want to make them clean and consistent. This patch cleans up a part of it.

Advertise a larger max read queue depth for qps, and gather the resource limits from fw and use them to avoid exhaustinq all the resources. Design: cxgb4: Obtain the max_ordird_qp and max_ird_adapter device params from FW at init time and pass them up to the ULDs when they attach. If these parameters are not available, due to older firmware, then hard-code the values based on the known values for older firmware. iw_cxgb4: Fix the c4iw_query_device() to report these correct values based on adapter parameters. ibv_query_device() will always return: max_qp_rd_atom = max_qp_init_rd_atom = min(module_max, max_ordird_qp) max_res_rd_atom = max_ird_adapter Bump up the per qp max module option to 32, allowing it to be increased by the user up to the device max of max_ordird_qp. 32 seems to be sufficient to maximize throughput for streaming read benchmarks. Fail connection setup if the negotiated IRD exhausts the available adapter ird resources. So the driver will track the amount of ird resource in use and not send an RI_WR/INIT to FW that would reduce the available ird resources below zero.

Change logic which determines our Physical Function at PCI Probe time. Now we read the PL_WHOAMI register and get the Physical Function. Pass Physical Function to Upper Layer Drivers in lld_info structure in the new field "pf" added to lld_info. This is useful for the cases where the PF, say PF4, is attached to a Virtual Machine via some form of "PCI Pass Through" technology and the PCI Function shows up as PF0 in the VM.

Select the appropriate hw mtu index and initial sequence number to optimize hw memory performance. Add new cxgb4_best_aligned_mtu() which allows callers to provide enough information to be used to [possibly] select an MTU which will result in the TCP Data Segment Size (AKA Maximum Segment Size) to be an aligned value. If an RTR message exhange is required, then align the ISS to 8B - 1 + 4, so that after the SYN the send seqno will align on a 4B boundary. The RTR message exchange will leave the send seqno aligned on an 8B boundary. If an RTR is not required, then align the ISS to 8B - 1. The goal is to have the send seqno be 8B aligned when we send the first FPDU.

In cases where the cm calls c4iw_modify_rc_qp() with the endpoint mutex held, they must be called with internal == 1. rx_data() and process_mpa_reply() are not doing this. This causes a deadlock because c4iw_modify_rc_qp() might call c4iw_ep_disconnect() in some !internal cases, and c4iw_ep_disconnect() acquires the endpoint mutex. The design was intended to only do the disconnect for !internal calls. Change rx_data(), FPDU_MODE case, to call c4iw_modify_rc_qp() with internal == 1, and then disconnect only after releasing the mutex. Change process_mpa_reply() to call c4iw_modify_rc_qp(TERMINATE) with internal == 1 and set a new attr flag telling it to send a TERMINATE message. Previously this was implied by !internal. Change process_mpa_reply() to return whether the caller should disconnect after releasing the endpoint mutex. Now rx_data() will do the disconnect in the cases where process_mpa_reply() wants to disconnect after the TERMINATE is sent. Change c4iw_modify_rc_qp() RTS->TERM to only disconnect if !internal, and to send a TERMINATE message if attrs->send_term is 1. Change abort_connection() to not aquire the ep mutex for setting the state, and make all calls to abort_connection() do so with the mutex held.

1) timedout endpoint processing can be starved. If there are continual CPL messages flowing into the driver, the endpoint timeout processing can be starved. This condition exposed the other bugs below. Solution: In process_work(), call process_timedout_eps() after each CPL is processed. 2) Connection events can be processed even though the endpoint is on the timeout list. If the endpoint is scheduled for timeout processing, then we must ignore MPA Start Requests and Replies. Solution: Change stop_ep_timer() to return 1 if the ep has already been queued for timeout processing. All the callers of stop_ep_timer() need to check this and act accordingly. There are just a few cases where the caller needs to do something different if stop_ep_timer() returns 1: 1) in process_mpa_reply(), ignore the reply and process_timeout() will abort the connection. 2) in process_mpa_request, ignore the request and process_timeout() will abort the connection. It is ok for callers of stop_ep_timer() to abort the connection since that will leave the state in ABORTING or DEAD, and process_timeout() now ignores timeouts when the ep is in these states. 3) Double insertion on the timeout list. Since the endpoint timers are used for connection setup and teardown, we need to guard against the possibility that an endpoint is already on the timeout list. This is a rare condition and only seen under heavy load and in the presense of the above 2 bugs. Solution: In ep_timeout(), don't queue the endpoint if it is already on the queue.

Move QP to TERMINATE instead to allow the peer to get the TERM message. This bug wasn't detectable until newer FW that moves connections out of RDMA mode as soon as an error is detected. QP can exit RTS before the last AE arrives. This was introduced by changes in the FW to kick connections out of RDMA mode as soon as an error is detected. A side effect of this is that the driver can move the QP out of RTS before the AE causing the connection to get kicked out of RDMA mode is processed. Fix for this is to always post async errors even if the QP is out of RTS.
