qdisc RED offload

Nogah says:

Add an offload support for RED qdisc for mlxsw driver.
The first patch adds the ability to offload RED qdisc by using
ndo_setup_tc. It gives RED three commands, to offload, change or delete
the qdisc, to get the qdisc generic stats and to get it's RED xstats.
There is no enforcement on a driver to offload or not offload the qdisc and
it is up to the driver to decide.
RED qdisc is first being created and only later graft to a parent (unless
it is a root qdisc). For that reason the return value of the offload
replace command that is called in the init process doesn't reflect actual
offload state. The offload state is determined in the dump function so it
can be reflected to the user. This function is also responsible for stats
update.

The patchses 2-3 change the name of TC_SETUP_MQPRIO & TC_SETUP_CBS to match
with the new convention of QDISC prefix.
The rest of the patchset is driver support for the qdisc. Currently only
as root qdisc that is being set on the default traffic class. It supports
only the following parameters of RED: min, max, probability and ECN mode.
Limit and burst size related params are being ignored at this moment.

---
v7->v8 internal: (external RFC->v1)
- patch 1/9:
 - unite the offload and un-offload functions
 - clean the OFFLOAD flag when the qdisc in not offloaded
- patch 2/9:
 - minor change to avoid a conflict
- patch 5/9:
 - check for bad min/max values
 - clean the offloaded qdisc after a bad config call

ila: make identifier format optional and other fixes

The identifier type and checksum neutral mapping bits are optional
in identifier formats. This patch set fixes the implementation to
make them optional and configurable.

Specific items:

  - Clean up checksum diff code in ILA
  - Add checksum neutral mapping auto so that checksum neutral
    mapping can be configured without requiring use of the C-bit
  - Add identifier type configuration and allow identifier
    type to be configured so that the identifier type field does
    not need to be present
  - Added ILA documention: ila.txt

I have fixes for ILA in iproute2 that will be poseted separately.

Tested: Ran netperf TCP_RR on various combinations of checksum
mode and the two supported identifier types.

v2:
  - Add proper sign off
  - In ILA LWT, only check prefix length includes identifier type
    if identifier type is enabled (ILA_ATYPE_USE_FORMAT).
  - Add a hook type so that it can be specified whether ILA
    translation is done on input or output route funciton in

Add a test for device cgroup controller.

The test loads a simple bpf program which logs all
device access attempts using trace_printk() and forbids
all operations except operations with /dev/zero and
/dev/urandom.

Then the test creates and joins a test cgroup, and attaches
the bpf program to it.

Then it tries to perform some simple device operations
and checks the result:

  create /dev/null (should fail)
  create /dev/zero (should pass)
  copy data from /dev/urandom to /dev/zero (should pass)
  copy data from /dev/urandom to /dev/full (should fail)

mlx5-updates-2017-11-04

This series includes:

From Huy: dscp to priority mapping for Ethernet packet.

===================================================
First six patches enable differentiated services code point (dscp) to
priority mapping for Ethernet packet. Once this feature is
enabled, the packet is routed to the corresponding priority based on its
dscp. User can combine this feature with priority flow control (pfc)
feature to have priority flow control based on the dscp.

Firmware interface:
Mellanox firmware provides two control knobs for this feature:
  QPTS register allow changing the trust state between dscp and
  pcp mode. The default is pcp mode. Once in dscp mode, firmware will
  route the packet based on its dscp value if the dscp field exists.

  QPDPM register allow mapping a specific dscp (0 to 63) to a
  specific priority (0 to 7). By default, all the dscps are mapped to
  priority zero.

Software interface:
This feature is controlled via application priority TLV. IEEE
specification P802.1Qcd/D2.1 defines priority selector id 5 for
application priority TLV. This APP TLV selector defines DSCP to priority
map. This APP TLV can be sent by the switch or can be set locally using
software such as lldptool. In mlx5 drivers, we add the support for net
dcb's getapp and setapp call back. Mlx5 driver only handles the selector
id 5 application entry (dscp application priority application entry).
If user sends multiple dscp to priority APP TLV entries on the same
dscp, the last sent one will take effect. All the previous sent will be
deleted.

The firmware trust state (in QPTS register) is changed based on the
number of dscp to priority application entries. When the first dscp to
priority application entry is added by the user, the trust state is
changed to dscp. When the last dscp to priority application entry is
deleted by the user, the trust state is changed to pcp.

When the port is in DSCP trust state, the transmit queue is selected
based on the dscp of the skb.

When the port is in DSCP trust state and vport inline mode is not NONE,
firmware requires mlx5 driver to copy the IP header to the
wqe ethernet segment inline header if the skb has it.
This is done by changing the transmit queue sq's min inline mode to L3.
Note that the min inline mode of sqs that belong to other features
such as xdpsq, icosq are not modified.
===================================================

Plus to the dscp series, some small misc changes are include as well:

From Inbar, Ethtool msglvl support and some debug prints in DCBNL logic
From Or Gerlitz, Enlarge the NIC TC offload table size
From Rabie, Initialize destination_flow struct to 0
From Feras, Add inner TTC table to IPoIB flow steering

SRIOV VFs without first disabling them. This case is explicitly
disallowed in any case and subsequent patches in this series
need to be able to replace the running set of reprs.

All cases where the return code used to be checked for the
nfp_app_reprs_set function have been removed.
As stated above, it is not possible for the current code to encounter a
case where reprs exist and need to be replaced.

Recent management FW images can perform full reinit of MAC cores
without requiring a reboot.  When loading the driver check if there
are changes pending and if so call NSP MAC reinit.  Full application
FW reload is still required, and all MACs need to be reinited at the
same time (not only the ones which have been reconfigured, and thus
potentially causing disruption to unrelated netdevs) therefore for
now changing MAC config without reloading the driver still remains
future work.
