f549e3521d cxgbe(4): Do not forward interrupts to queues with freelists. This
leaves the firmware event queue (fwq) as the only queue that can take
interrupts for others.

This simplifies cfg_itype_and_nqueues and queue allocation in the driver
at the cost of a little (never?) used configuration.  It also allows
service_iq to be split into two specialized variants in the future.

718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

ec7f8d58b9 CXGBE: fix big-endian behaviour
The setbit/clearbit pair casts the bitfield pointer
to uint8_t* which effectively treats its contents as
little-endian variable. The ffs() function accepts int as
the parameter, which is big-endian. Use uint8_t here to
avoid mismatch, as we have only 4 doorbells.

d05554bb99 The remote DMA TCP portspace selector, RDMA_PS_TCP, is used for both
iWarp and RoCE in ibcore. The selection of RDMA_PS_TCP can not be used
to indicate iWarp protocol use. Backport the proper IB device
capabilities from Linux upstream to distinguish between iWarp and
RoCE. Only allocate the additional socket required for iWarp for RDMA
IDs when at least one iWarp device present. This resolves
interopability issues between iWarp and RoCE in ibcore

e8fd18f306 Shorten list of arguments to mbuf external storage freeing function.
All of these arguments are stored in m_ext, so there is no reason
to pass them in the argument list.  Not all functions need the second
argument, some don't even need the first one.  The second argument
lives in next cache line, so not dereferencing it is a performance
gain.  This was discovered in sendfile(2), which will be covered by
next commits.

The second goal of this commit is to bring even more flexibility
to m_ext mbufs, allowing to create more fields in m_ext, opaque to
the generic mbuf code, and potentially set and dereferenced by
subsystems.

714d3ee05b cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0.
Changes since 1.16.26.0 for all three firmwares are listed below.  This
list was obtained from the Release Notes of the Chelsio Unified Wire
v3.5.05 release for Linux.

T6 Firmware
++++++++++++
================================================================================
Version : 1.16.63.0
Date    : 09/29/2017
================================================================================

Fixes
-----

BASE:
- Fixed a fw crash when configured traffic rate limit is less than 10kbps.
- Fixed traffic rate limiting for smaller traffic rate value.

ETH:
- Fixed 40G link failure when interface is toggled.
- Fixed adapter crash when interface is toggled during traffic.
- Fixed 25G link failure when PEER only supports consortium mode autoneg
  for 25G.
- Fixed 100G optics link failure when cable is plugged in after bringing up
  the interface.
- Enable RS FEC as default if speed is 100G.
- Fixed DCBX configuration refresh failure.

OFLD
- Fixed 0B iWARP ingress read failure.
- Fixed iWARP SRQ reuse failure.

FOiSCSI:
- Fixed vlan interface ping failure.
- Fixed target discovery failures.
- Fixed mutual chap login failure.

================================================================================
Version : 1.16.59.0
Date    : 09/05/2017
================================================================================

FIXES
-----

BASE:
- Fixed fw crash caused by MC parity error in SO adapters.
- Generate Timer0Int interrupt if fw crashes due to unaligned access error. Host
  driver must look into PCIE_FW register to see if any fw fatal error has
  encountered. If PCIE_FW doesn't indicate any error then driver must ignore this
  interrupt.
- Fixed receive buffer threshold settings which was resulting in error frames on
  receive side.

ETH:
- Fixed an issue in connection traffic shaping when
  FLOWC_WR->FW_FLOWC_MNEM_SCHEDCLASS is not received in first WR on the connection.
- Fixed link failure when speed is changed from 10G-1G-10G due to incorrect flag
  check.
- Fixed improper LED behaviour for blink test and when traffic is running.
- Removed storage of previous fec settings from fw. Driver needs to pass the user
  settings whenever a new module is plugged in as fw resets these when a module is
  unplugged.

OFLD
- OVS offload: TP cache is flushed periodically to get the accuate filters stats
  (hit count).

ENHANCEMENTS
------------

BASE:
- Ring backbone feature added. New FW_PARAMS_PARAM_DEV_RING_BACKBONE param type
  added to query and enable ring backbone support.
- VNI support added for filtering. New entry_type FW_VI_MAC_TYPE_EXACTMAC_VNI
  added to FW_VI_MAC_CMD.
- Added new API FW_PARAM_PARAM_DEV_MPSBGMAP to read the priority to buffer group
  mapping for the ports.
- FW_PARAMS_PARAM_DEV_TPCHMAP API added to read the port to channel mapping.
- HMA (Host memory access) support added. New FW_HMA_CMD and
  FW_PARAMS_PARAM_DEV_HMA_SIZE added to query and configure the HMA. It
  enables the memfree support (256 connections) for iwarp.
- PTP support enabled.

ETH:
- Added consortium mode 50G support.
- Added the ability to allow only selected speeds to be advertised during auto
  negotiation.
- Increased port capability from 16 to 32 bits to support more speeds.
  FW_PARAMS_PARAM_PFVF_PORT_CAPS32 added to query whether fw supports 16 or 32
  bit port capability.

OFLD:
- RDMA Write with immediate support added (iwarp 2.0 feature)
- FW_TLS_KEYCTX_TX_WR removed and security key management moved to driver.
- 256 offloaded connections support for iwarp on SO adapters.

iSCSI:
- New param FW_PARAMS_PARAM_DEV_PPOD_EDRAM added for iscsi ppod configuration
  in EDRAM (performance improvement).

FOiSCSI:
- iSCSI Command offload target support added.

FOFCoE:
- FCoE support enabled.

91a65e2f6b Avoid reusing the wrong buffer for a DDP AIO request.
To optimize the case of ping-ponging between two buffers, the DDP code
caches the last two buffers used keeping the pages wired and page pods
stored in the NIC's RAM.  If a new aio_read() request uses one of the
same buffers, then the work of holding pages, etc. can be avoided.
However, the starting virtual address of an aio buffer was not saved,
only the page count, length, and initial page offset.  Thus, an
aio_read() request could match a different buffer in the address
space.  (Earlier during development vm_fault_hold_quick_pages() was
always called and the vm_page_t values were compared, but that was
eventually removed without being adequately replaced.)  Fix by storing
the starting virtual address and comparing that (along with other
fields) to determine if a buffer can be reused.

- commit_wrq_wr must examine the cookie's pidx and ndesc with the
  queue's lock held.  Otherwise there is a bad race when incomplete WRs
  are being completed and commit_wrq_wr for the WR that is ahead in the
  queue updates the next incomplete WR's cookie's pidx/ndesc but the
  commit_wrq_wr for the second one is using stale values that it read

the current state to determine whether to generate a link-state change
notification.  This fixes a bug introduced in r321063 that caused the
driver to sometimes skip these notifications.

f856f099cb cxgbe(4): Initial import of the "collect" component of Chelsio unified
debug (cudbg) code, hooked up to the main driver via an ioctl.

The ioctl can be used to collect the chip's internal state in a
compressed dump file.  These dumps can be decoded with the "view"
component of cudbg.
