79dabbb716 ibmvnic: Remove code to request error information
When backing device firmware reports an error, it provides an
error ID, which is meant to be queried for more detailed error
information. Currently, however, an error ID is not provided by
the Virtual I/O server and there are not any plans to do so. For
now, it is always unfilled or zero, so request_error_information
will never be called.  Remove it.

7395a88455 liquidio: avoided acquiring post_lock for data only queues
All control commands (soft commands) goes through only Queue 0
(control and data queue). So only queue-0 needs post_lock,
other queues are only data queues and does not need post_lock

Added a flag to indicate the queue can be used for soft commands.

If this flag is set, post_lock must be acquired before posting
a command to the queue.
If this flag is clear, post_lock is invalid for the queue.

adfb442dbb cxgb4: mk_act_open_req() buggers ->{local, peer}_ip on big-endian hosts
Unlike fs.val.lport and fs.val.fport, cxgb4_process_flow_match()
sets fs.val.{l,f}ip to net-endian values without conversion - they come
straight from flow_dissector_key_ipv4_addrs ->dst and ->src resp.  So
the assignment in mk_act_open_req() ought to be a straight copy.

	As far as I know, T4 PCIe cards do exist, so it's not as if that
thing could only be found on little-endian systems...

333e2f2cea i40e: fix i40e_add_queue_stats data pointer update
This function accidentally failed to update the data pointer, which
caused the reported stats to be incorrect. Additionally, statistics
which follow queue stats in the output would potentially read non-zeroed
garbage data from the ethtool buffer.

This occurred because the data double pointer was not dereferenced
before incrementing the size.

Additionally, make sure this issue is more visible by adding a WARN_ONCE
to the i40e_get_ethtool_stats function. This warning will trigger
whenever the data pointer is not at the expected address, similar to the
check that we make in the i40e_get_stat_strings() function.

6e2feaa344 i40e: fix warning about shadowed ring parameter
In commit 147e81ec75 ("i40e: Test memory before ethtool alloc succeeds")
code was added to handle ring allocation on systems with low memory.

It shadowed the ring parameter pointer by introducing a local ring
pointer inside the for loop. Most of the code in the loop already just
accessed the ring via &rx_rings[i]. Since most of the code already does
this, just remove the local variable.

If someone considers it worth keeping a local around, they should use it
for the whole section instead of just a couple of accesses.

This fixes a warning when -Wshadow is enabled

Commit c61c8fe1d5 ("i40e: Implement an ethtool private flag to stop
LLDP in FW") added an extra for-loop which added a shadowing 'i'
variable as the index.

However, the local variable i already exists, and we already use it as
a loop index. Additionally, at this point, there is no further use of
the variable, so it's safe to simply overwrite the variable contents.

This fixes a -Wshadow warning which has started being enabled on some
distributions

f25848d4cd i40e: convert priority flow control stats to use helpers
The priority flow control statistics are laid out in the stats structure
using arrays. This made it unwieldy to use as part of an i40e_stats
array.

Add a new structure type, i40e_pfc_stats, and a helper function
i40e_get_pfc_stats which can return the stats for a given priority
value as an i40e_pfc_stats structure.

Use this to create an i40e_stats array, which we'll use to format and
copy the strings and stats into the supplied buffers.

This reduces even more boiler plate code in i40e_get_ethtool_stats and
i40e_get_stat_strings.

An alternative would be to modify the structure definition for the pfc
stats, but this is more invasive to the rest of the code base.

Note that a macro was used to setup the copy of stats from the
pf->stats, as this reduces the chance of typos in the code names. It
will produce a checkpatch.pl warning due to re-use of a macro argument.
In this case, it should be safe, as the macro will fail to compile in
cases where the argument is not a simple structure member name, and thus
arguments with side effects should not be an issue.

1510ae0be2 i40e: convert VEB TC stats to use an i40e_stats array
The VEB TC stats are currently implemented with separate parsing,
instead of using the i40e_stats array and associated helper functions.
This is likely because the stats rely on embedding the TC number into
the stat name.

Update i40e_add_stat_strings to take variadic arguments, and use these
to vsnprintf the i40e_stats string as a string containing format
specifiers.

Create a stats array for the VEB TC related stats,
i40e_gstrings_veb_tc_stats, and use this along with the helper functions
to remove the specialized boiler plate code.

Always call i40e_add_ethtool_stats for both this array and the general
VEB stats array. This ensures that we zero out any memory in case it was
not zero-allocated for us.

This ultimately results in less boiler plate code for the
i40e_get_stat_strings and i40e_get_ethtool_stats.

91f0654461 i40e: add helper function for copying strings from stat arrays
Many of the ethtool statistics use the same basic logic for copying
strings into the supplied buffer. A set of stats are stored in a const
array of i40e_stats structures, and we apply these all together.

Simplify the stats code by introducing a helper function which can take
a stats array and copy the strings into the buffer, updating the buffer
pointer as we go.

We use a macro to implement i40e_add_stat_strings so that ARRAY_SIZE can
be used on the array passed in. This ensures that we always use the
matching size in __i40e_add_stat_strings.

More complex stats currently do not use i40e_stats arrays, usually due
to custom formatted strings, or because the stats are not laid out in
the expected way. These stats will be updated to use the helper function
in separate future patches.

f25da51fdc ieee802154: hwsim: add replacement for fakelb
This patch adds a new virtual driver mac802154_hwsim which is based on
the fakelb driver.
The fakelb driver will get deprecated and hopefully removed someday.
The main reason for doing this step is to rename the driver to
mac802154_hwsim to have a similar naming scheme as mac80211_hwsim,
which is more popular in the 802.11 wireless word and the idea is the
same behind this driver.

The new features of this driver are to have knowledge about connected
edges, which can be changed during runtime. This offers a testing
environment for routing protocols e.g. RPL.
The default behaviour is still as fakelb: two radios connected to each
other. New added radios during runtime will not be connected to other
wpan_hwsim instances.

The netlink api is not namespace aware on purpose, only the registered
wpan_phy's can be moved to namespaces. The physical layer according to
wiresless "air" communication can be handled across namespaces.

Furthermore the edges can be weighted with the LQI value according IEEE
802.15.4 which offers additional handling to mark bad or good connection
indicators to other connected virtual phys.

Merge tag 'wireless-drivers-next-for-davem-2018-08-05' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
wireless-drivers-next patches for 4.19

This time a bigger pull request as we have two new Mediatek drivers
MT76x2u (CONFIG_MT76x2U) and MT76x0U (CONFIG_MT76x0U). Also iwlwifi got
support for the new IEEE 802.11ax standard, the successor for
802.11ac. And naturally smaller new features and bugfixes all over.

Major changes:

wcn36xx

* fix WEP in client mode

wil6210

* add support for Talyn-MB (Talyn ver 2.0) device

* add support for enhanced DMA firmware feature

iwlwifi

* implement 802.11ax D2.0

* support for the new 22560 device family

* new PCI IDs for 22000 and 22560

qtnfmac

* implement cfg80211 power management callback

* enable multiple SSIDs scan support

* qtnfmac: implement basic WoWLAN support

mt7601u

* fall back to software encryption for hw unsupported ciphers

* enable 802.11 Management Frame Protection (MFP)

mt76

* support setting RTS threshold

* add USB support

* add support for MT76x2u devices

* add support for MT76x0U devices

mwifiex

* allow user space to set all other IEs except WMM IE

rsi

* add firmware support for AP+BT dual mode

7b81953066 mlxsw: spectrum: Configure MC-aware mode on mlxsw ports
In order to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.

Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8.

ETS elements for TCs 8..15 thus need to be configured as well. Extend
mlxsw_sp_port_ets_init() so that it maps each of them to the same
subgroup as their corresponding TC from the range 0..7, such that TCs X
and X+8 map to the same subgroup.

The existing code configures TCs with strict priority. So far this was
immaterial, because each TC had its own subgroup. Now that two TCs share
a subgroup it becomes important. TCs are prioritized in order of 7, 6,
..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being
deprioritized. Since that's what's needed, keep that configuration as it
is, and configure the new TCs likewise.

Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to
enable MC-aware mode on each port.

aabfc016e9 bnxt_en: Do not use the CNP CoS queue for networking traffic.
The CNP CoS queue is reserved for internal RDMA Congestion Notification
Packets (CNP) and should not be used for a TC.  Modify the CoS queue
discovery code to skip over the CNP CoS queue and to reduce
bp->max_tc accordingly.  However, if RDMA is disabled in NVRAM, the
the CNP CoS queue can be used for a TC.

Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the
firmware that the driver is compliant with the latest spec.  With
that, the firmware can return expanded RSS profile IDs that the driver
checks to setup the proper gso_type for GRO-HW packets.  But instead
of checking for the new profile IDs, we check the IP_TYPE flag
in TPA_START which is more straight forward than checking a list of
profile IDs.
