If using a demand-dialled PPP unit for a PPP multilink master, the pppd daemon needs to reset the sequence counter between two connections. This allows the daemon to reuse the PPP unit instead of destroying and recreating it. As there is no API to reset the counter, this patch resets the counter whenever the SC_MULTILINK flag is set.

This commit enhances the iwarp driver to optionally keep a log of rdma work request timining data for kernel mode QPs. If iw_cxgb4 module option c4iw_wr_log is set to non-zero, each work request is tracked and timing data maintained in a rolling log that is 4096 entries deep by default. Module option c4iw_wr_log_size_order allows specifing a log2 size to use instead of the default order of 12 (4096 entries). Both module options are read-only and must be passed in at module load time to set them. IE: modprobe iw_cxgb4 c4iw_wr_log=1 c4iw_wr_log_size_order=10 The timing data is viewable via the iw_cxgb4 debugfs file "wr_log". Writing anything to this file will clear all the timing data. Data tracked includes: - The host time when the work request was posted, just before ringing the doorbell. The host time when the completion was polled by the application. This is also the time the log entry is created. The delta of these two times is the amount of time took processing the work request. - The qid of the EQ used to post the work request. - The work request opcode. - The cqe wr_id field. For sq completions requests this is the swsqe index. For recv completions this is the MSN of the ingress SEND. This value can be used to match log entries from this log with firmware flowc event entries. - The sge timestamp value just before ringing the doorbell when posting, the sge timestamp value just after polling the completion, and CQE.timestamp field from the completion itself. With these three timestamps we can track the latency from post to poll, and the amount of time the completion resided in the CQ before being reaped by the application. With debug firmware, the sge timestamp is also logged by firmware in its flowc history so that we can compute the latency from posting the work request until the firmware sees 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.

This adds support for hardware loopback in SJA1000 by utilising its self reception request (SRR) feature. Upon SRR the message is transmitted and received simultaneously, meaning you can't have hardware loopback without actually sending a message to the CAN bus in case of SJA1000.
