there can be many stations.

Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble

Hence implement a dummy callback just to say

in software.

In general, p2p management interfaces cannot send vif-specific commands

If the vif is a p2p mgmt vif, block some mac80211 ops.

otherwise p2p packets come out with arbitrary rates.
Since wpa_supplicant currently doesn't support standalone
p2p device mode (without another attached managed interface),
add p2p device to the allowed interface combinations without
decreasing the allowed station count.
Moreover, increase the station count in some cases, as AP
mode usually starts as station interface, and the AP interface

mwifiex: remove redundant reset of cmd_wait_q status
mwifiex_cancel_pending_ioctl is called only from
mwifiex_cmd_timeout_func. There the wait_q status is set to
-ETIMEDWAIT before calling this function. Whether we reset the status
to -1 or leave it at -ETIMEDWAIT at end doesn't matter since both
are != 0 hence mean failure

mwifiex: sdio: reset adapter using mmc_hw_reset
Since

sdio cards can be power cycled using mmc_hw_reset.
The use mmc_remove_host/mmc_add_host is discouraged, because these are
internal functions to the mmc core and should only be used by mmc hosts

Support for the system suspend/resume.
In preparation for the run-time PM, implementation made
run-time PM friendly: common for system and run-time PM

parameter value is always false currently.
For debug purposes, "PM" debug category introduced.
Policy: AP-like interface can't be suspended; otherwise
suspend is allowed. Hardware brought down if interface
was up. Connection, if existed, get lost.
Interface will be brought up upon resume if it was up

wil6210: allow to handle Rx on 2 cores
Allow network stack part of Rx processing to run on separate core,
relaxing CPU utilization on the core used for Rx NAPI.
If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
to enable RPS. The core for processing the rx skb is determined by RPS
mechanism according to rx_cpus bit mask which is configured at user level.
For processing skbs on different core from the core which processes
the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.
