====================
pull-request: can-next 2014-07-15
this is a pull request of 4 patches for net-next/master.
Prabhakar Lad contributes a patch that converts the c_can driver to use
the devm api. The remaining four patches by Nikita Edward Baruzdin
improve the SJA1000 driver with loopback testing support and introduce
a new testing mode presume ack, for successful transmission even if no
ACK is received.

Expand the phy speed/duplex settings array to support more
than just baseT features. This change adds entries to support
the following additional speed/duplex/media types:
SUPPORTED_10000baseKR_Full
SUPPORTED_10000baseKX4_Full
SUPPORTED_2500baseX_Full
SUPPORTED_1000baseKX_Full
Additionally, it changes the 10GbE baseT entry from using the
hardcoded value 10000 to the SPEED_10000 define.

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.

With ingress WRITE or READ RESPONSE errors, HW provides the offending

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.

SJA1000 has a self test mode (STM) which does not require
acknowledgement for the successful message transmission. In this mode a
node test is possible without any other active node on the bus.
This patch adds a possibility to set STM for SJA1000 controller through
specifying the corresponding CAN_CTRLMODE_PRESUME_ACK netlink flag.

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.

Please pull this batch of updates intended for the 3.17 stream...
This is primarily a Bluetooth pull. Gustavo says:
"A lot of patches to 3.17. The bulk of changes here are for LE support.
The 6loWPAN over Bluetooth now has it own module, we also have support for
background auto-connection and passive scanning, Bluetooth device address
provisioning, support for reading Bluetooth clock values and LE connection
parameters plus many many fixes."
The balance is just a pull of the wireless.git tree, to avoid some
pending merge problems.
