we reach each basic filter and how many times we pass the

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
use "" instead of "\0" because "" is used elsewhere in the kernel and

Commit 8ce5f84157 ("of: Remove struct device_node.type pointer")
removed struct device_node.type pointer, but the conversion to use
of_node_is_type() accessor was missed in chrp_init_IRQ().

Some hardware (e.g. MediaTek MT7603) cannot report A-MPDU length in tx status
information. Add support for a flag to indicate that, to allow minstrel_ht
to use a fixed value in its internal calculation (which gives better results
than just defaulting to 1).

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.
