It establishes passive open connection through firmware work request. Passive
open connection will go through this path as now instead of listening server we

offload queue. After this driver tries to establish the connection using

It enables establishing active open connection using fw_ofld_connection work
request when cpl_act_open_rpl says TCAM full error which may be because
of LE hash collision. Current support is only for IPv4 active open connections.

Sets ntuple bits in active open requests. For T4 firmware greater than 1.4.10.0
ntuple bits are required to be set.

Adds nocong and enable_ecn module parameter options.

It supports establishing passive open connection through firmware filter work
request. Passive open connection will go through this path as now instead of
listening server we create a server filter which will redirect the incoming SYN
packet to the offload queue.

It divides filter region into regular filters and server filter portion. It
introduces new server filter region which will be exclusively used for creating
server filters. This region will not overlap with regular filter region.

It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE
hash collision path. This new stid will be used to open server filter in the
filter region.

The T4 architecture is capable of filtering ingress packets at line rate
using the rule in TCAM. If packet hits a rule in the TCAM then it can be either
dropped or passed to the receive queues based on a rule settings.

This patch adds framework for managing filters and to use T4's filter
capabilities. It constructs a Firmware Filter Work Request which writes the
filter at a specified index to get the work done. It hosts shadow copy of
ingress filter entry to check field size limitations and save memory in the
case where the filter table is large.

Pull target updates from Nicholas Bellinger:
 "It has been a very busy development cycle this time around in target
  land, with the highlights including:

   - Kill struct se_subsystem_dev, in favor of direct se_device usage
     (hch)
   - Simplify reservations code by combining SPC-3 + SCSI-2 support for
     virtual backends only (hch)
   - Simplify ALUA code for virtual only backends, and remove left over
     abstractions (hch)
   - Pass sense_reason_t as return value for I/O submission path (hch)
   - Refactor MODE_SENSE emulation to allow for easier addition of new
     mode pages.  (roland)
   - Add emulation of MODE_SELECT (roland)
   - Fix bug in handling of ExpStatSN wrap-around (steve)
   - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
   - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
   - Convert ib_srpt to use modern target_submit_cmd caller + drop
     legacy ioctx->kref usage (nab)
   - Convert ib_srpt to use modern target_submit_tmr caller (nab)
   - Add link_magic for fabric allow_link destination target_items for
     symlinks within target_core_fabric_configfs.c code (nab)
   - Allocate pointers in instead of full structs for
     config_group->default_groups (sebastian)
   - Fix 32-bit highmem breakage for FILEIO (sebastian)

  All told, hch was able to shave off another ~1K LOC by killing the
  se_subsystem_dev abstraction, along with a number of PR + ALUA
  simplifications.  Also, a nice patch by Roland is the refactoring of
  MODE_SENSE handling, along with the addition of initial MODE_SELECT
  emulation support for virtual backends.

  Sebastian found a long-standing issue wrt to allocation of full
  config_group instead of pointers for config_group->default_group[]
  setup in a number of areas, which ends up saving memory with big
  configurations.  He also managed to fix another long-standing BUG wrt
  to broken 32-bit highmem support within the FILEIO backend driver.

  Thank you again to everyone who contributed this round!"

This reverts commit 53b87cf0.

It causes odd bootup problems on x86-64.  Markus Trippelsdorf gets a
repeatable oops, and I see a non-repeatable oops (or constant stream of
messages that scroll off too quickly to read) that seems to go away with
this commit reverted.

So we don't know exactly what is wrong with the commit, but it's
definitely problematic, and worth reverting sooner rather than later.

Pull x86 ACPI update from Peter Anvin:
 "This is a patchset which didn't make the last merge window.  It adds a
  debugging capability to feed ACPI tables via the initramfs.

  On a grander scope, it formalizes using the initramfs protocol for
  feeding arbitrary blobs which need to be accessed early to the kernel:
  they are fed first in the initramfs blob (lots of bootloaders can
  concatenate this at boot time, others can use a single file) in an
  uncompressed cpio archive using filenames starting with "kernel/".

  The ACPI maintainers requested that this patchset be fed via the x86
  tree rather than the ACPI tree as the footprint in the general x86
  code is much bigger than in the ACPI code proper."

This reverts commit f269ae04.

It turns out it causes a very noticeable interactivity regression with
CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
terminal window, while scrolling in a browser - the autogrouping means
that the two end up in separate cgroups, and the browser should be
smooth as silk despite the high load).

Says Paul Turner:
 "It seems that the update-throttling on the wake-side is reducing the
  interactive tasks' ability to preempt.  While I suspect the right
  longer term answer here is force these updates only in the
  cross-cgroup case; this is less trivial.  For this release I believe
  the right answer is either going to be a revert or restore the updates
  on the enqueue-side."

  A NACK is probably the right thing. I was mostly converting a few
  other drivers which used some simple, common patterns to use my new
  common code, but this driver was missing it altogether. It looks like
  there may be bigger issues, though, as you point out.

  As noted earlier, I don't have much interest in this driver. I agree
  that there are some other issues with the driver; I think it leaks
  memory if it is ever allowed to unload, for one. Feel free to submit
  an alternative patch to prevent this driver from being built as a
  module.
