dpaa2-eth: add debugfs statistics
This patch set exports detailed driver counters through debugfs.
Counters which are already available through ethtool are now
presented in a structured manner (per-core, per-FQ and
per-channel) in debugfs.
The first patch is changing the dpaa2_eth_queue_count into a macro
(in order to avoid a warning) while the second one is adding the
debugfs support.
Changes in v2:

This series extends strict argument checking to doit handlers
of the GET* nature. This is a bit tricky since strict checking

iproute2 did not have a release with strick checks enabled,
and it will only need a minor one-liner to pass strick checks

On multiqueue network devices, RPS maps are configured independently
for each receive queue through /sys/class/net/$DEV/queues/rx-*.
On virtio-net currently all packets use the map from rx-0, because the
real rx queue is not known at time of map lookup by get_rps_cpu.
Call skb_record_rx_queue in the driver rx path to make lookup work.
Recording the receive queue has ramifications beyond RPS, such as in
sticky load balancing decisions for sockets (skb_tx_hash) and XPS.

This is equivalent to just "\0". Nick pointed out that it is smarter to

Allow user to override STBC configuration for Rx and Tx spatial streams.
In practice RX/TX STBC settings can be modified using appropriate
options in wpa_supplicant configuration file:
tx_stbc=-1..1
rx_stbc=-1..3
This functionality has been added to wpa_supplicant in commit cdeea70f59d0.
In FullMAC case these STBC options are passed to drivers by cfg80211
connect callback in fields of cfg80211_connect_params structure.
However for mac80211 drivers, e.g. for mac80211_hwsim,
overrides for STBC settings are ignored.
The reason why RX/TX STBC capabilities are not modified for mac80211
drivers is as follows. All drivers need to specify supported HT/VHT
overrides explicitly: see ht_capa_mod_mask and vht_capa_mod_mask fields
of wiphy structure. Only supported overrides will be passed to drivers by
cfg80211_connect and cfg80211_mlme_assoc operations: see bitwise 'AND'
performed by cfg80211_oper_and_ht_capa and cfg80211_oper_and_vht_capa.
This commit adds RX/TX STBC HT capabilities to mac80211_ht_capa_mod_mask,
allowing their modifications, as well as applies requested STBC
modifications in function ieee80211_apply_htcap_overrides.

This adds airtime accounting and scheduling to the mac80211 TXQ
scheduler. A new callback, ieee80211_sta_register_airtime(), is added
that drivers can call to report airtime usage for stations.
When airtime information is present, mac80211 will schedule TXQs
(through ieee80211_next_txq()) in a way that enforces airtime fairness
between active stations. This scheduling works the same way as the ath9k
in-driver airtime fairness scheduling. If no airtime usage is reported
by the driver, the scheduler will default to round-robin scheduling.
For drivers that don't control TXQ scheduling in software, a new API
function, ieee80211_txq_may_transmit(), is added which the driver can use
to check if the TXQ is eligible for transmission, or should be throttled to
enforce fairness. Calls to this function must also be enclosed in
ieee80211_txq_schedule_{start,end}() calls to ensure proper locking.
The API ieee80211_txq_may_transmit() also ensures that TXQ list will be
aligned aginst driver's own round-robin scheduler list. i.e it rotates
the TXQ list till it makes the requested node becomes the first entry
in TXQ list. Thus both the TXQ list and driver's list are in sync.

This adds an API to mac80211 to handle scheduling of TXQs. The interface
between driver and mac80211 for TXQ handling is changed by adding two new
functions: ieee80211_next_txq(), which will return the next TXQ to schedule
in the current round-robin rotation, and ieee80211_return_txq(), which the
driver uses to indicate that it has finished scheduling a TXQ (which will
then be put back in the scheduling rotation if it isn't empty).
The driver must call ieee80211_txq_schedule_start() at the start of each
scheduling session, and ieee80211_txq_schedule_end() at the end. The API
then guarantees that the same TXQ is not returned twice in the same
session (so a driver can loop on ieee80211_next_txq() without worrying
about breaking the loop.
Usage of the new API is optional, so drivers can be ported one at a time.
In this patch, the actual scheduling performed by mac80211 is simple
round-robin, but a subsequent commit adds airtime fairness awareness to the
scheduler.

In ieee80211_rx_h_mesh_fwding, we increment the 'dropped_frames_ttl'

destined for other hosts, we stop processing the frame at that point.
For multicast frames, we do not rebroadcast it in this case, but we
do pass the frame up the stack to process it on this STA. That
doesn't match the usual definition of "dropped," so don't count
those as such.

Previously the identifier used for indirect block callback registry
and for block rule cb registry (when done via indirect blocks) was the
pointer to the tunnel netdev we were interested in receiving updates on.
This worked fine if a single PF existed that registered one callback for
the tunnel netdev of interest. However, if multiple PFs are in place then
the 2nd PF tries to register with the same tunnel netdev identifier. This
leads to EEXIST errors and/or incorrect cb deletions.
Prevent this conflict by using the rpriv pointer as the identifier for
netdev indirect block cb registry, allowing each PF to register a unique
callback per tunnel netdev. For block cb registry, the same PF may
register multiple cbs to the same block if using TC shared blocks.
Instead of the rpriv, use the pointer to the allocated indr_priv data as
the identifier here. This means that there can be a unique block callback
for each PF/tunnel netdev combo.

When an ethernet frame is padded to meet the minimum ethernet frame
size, the padding octets are not covered by the hardware checksum.
Fortunately the padding octets are usually zero's, which don't affect
checksum. However, we have a switch which pads non-zero octets, this
causes kernel hardware checksum fault repeatedly.
Prior to:
commit '88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE ...")'
skb checksum was forced to be CHECKSUM_NONE when padding is detected.
After it, we need to keep skb->csum updated, like what we do for RXFCS.
However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP
headers, it is not worthy the effort as the packets are so small that
CHECKSUM_COMPLETE can't save anything.

Digging deeper: The files were imported from the iproute2 repository with

Looking at the iproute2 repository at

the following commit is the equivivalent:

That commit explicitly removes the boiler plate and relicenses the code
