01285747aa cxgbe(4): Various link/media related improvements.
- Deal with changes to port_type, and not just port_mod when a
  transceiver is changed.  This fixes hot swapping of transceivers of
  different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or
  SFP28 in a SFP28 port, etc.).

- Always refresh media information for ifconfig if the port is down.
  The firmware does not generate tranceiver-change interrupts unless at
  least one VI is enabled on the physical port.  Before this change
  ifconfig diplayed potentially stale information for ports that were
  administratively down.

- Always recalculate and reapply L1 config on a transceiver change.

- Display PAUSE settings in ifconfig.  The driver sysctls for this
  continue to work as well.

4623e047a7 Add explicit handling for requests with an empty payload.
- For HMAC requests, construct a special input buffer to request an empty
  hash result.
- For plain cipher requests and requests that chain an AES cipher with an
  HMAC, fail with EINVAL if there is no cipher payload.  If needed in
  the future, chained requests that only contain AAD could be serviced as
  HMAC-only requests.
- For GCM requests, the hardware does not support generating the tag for
  an AAD-only request.  Instead, complete these requests synchronously
  in software on the assumption that such requests are rare.

d68990a14c Fail large requests with EFBIG.
The adapter firmware in general does not accept PDUs larger than 64k - 1
bytes in size.  Sending crypto requests larger than this size result in
hangs or incorrect output, so reject them with EFBIG.  For requests
chaining an AES cipher with an HMAC, the firmware appears to require
slightly smaller requests (around 512 bytes).

5033c43b7a Add a driver for the Chelsio T6 crypto accelerator engine.
The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.

Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms.  The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.

Note that this driver is still under active development and testing and
may not yet be ready for production use.  It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.

To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver.  These can be done by setting the following
tunables before loading the cxgbe(4) driver:

    hw.cxgbe.config_file=uwire
    hw.cxgbe.cryptocaps_allowed=-1

6790499792 cxgbe/t4_tom: Per-connection rate limiting for TCP sockets handled by
the TOE.  For now this capability is always enabled in kernels with
options RATELIMIT.  t4_tom will check if_capenable once the base driver
gets code to support rate limiting for any socket (TOE or not).

This was tested with iperf3 and netperf ToT as they already support
SO_MAX_PACING_RATE sockopt.  There is a bug in firmwares prior to
1.16.45.0 that affects the BSD driver only and results in rate-limiting
at an incorrect rate.  This will resolve by itself as soon as 1.16.45.0
or later firmware shows up in the driver.

017296dbb6 cxgbe/iw_cxgbe: fix various double-close panics with iWARP sockets.
Sockets representing the TCP endpoints for iWARP connections are
allocated by the ibcore module.  Before this revision they were closed
either by the ibcore module or the iw_cxgbe hardware driver depending on
the state transitions during connection teardown.  This is error prone
and there were cases where both iw_cxgbe and ibcore closed the socket
leading to double-free panics.  The fix is to let ibcore close the
sockets it creates and never do it in the driver.

- Use sodisconnect instead of soclose (preceded by solinger = 0) in the
  driver to tear down an RDMA connection abruptly.  This does what's
  intended without releasing the socket's fd reference.

- Close the socket in ibcore when the iWARP iw_cm_id is destroyed.  This
  works for all kinds of sockets: clients that initiate connections,
  listeners, and sockets accepted off of listeners.

Active Open:
- Save the socket's vnet at the time of the active open (t4_connect) and
  switch to it when processing the reply (do_act_open_rpl or
  do_act_establish).

Passive Open:
- Save the listening socket's vnet in the driver's listen_ctx and switch
  to it when processing incoming SYNs for the socket.
- Reject SYNs that arrive on an ifnet that's not in the same vnet as the
  listening socket.

CLIP (Compressed Local IPv6) table:
- Add only those IPv6 addresses to the CLIP that are in a vnet
  associated with one of the card's ifnets.

Misc:
- Set vnet from the toepcb when processing TCP state transitions.
- The kernel sets the vnet when calling the driver's output routine
  so t4_push_frames runs in proper vnet context already.  One exception
  is when incoming credits trigger tx within the driver's ithread.  Set
  the vnet explicitly in do_fw4_ack for that case.

c70c4d71de The iw_cxgb and iw_cxgbe drivers should not use a FreeBSD device_t where
a linuxkpi style device is expected.  If OFED/linuxkpi actually starts
using this field then we'll have to figure out whether to create fake
devices for these drivers or have linuxkpi deal with NULL device.

This mismatch was first reported as part of D6585.

c88fa71928 cxgbe(4): Update T4, T5 and T6 firmwares to 1.16.26.0. Changelog for
all public firmwares for all chips since the last release (1.15.37.0)
follows (it's a straight copy-paste from the Release Notes for the
12/30/2016 Unified Wire release on Chelsio's website).

T6 Firmware
++++++++++++

Version : 1.16.26.0
