The driver can support this by implementing the cfg80211 callbacks

the netdev to identify what to do, which is incorrect for
the P2P_DEVICE support, it needs to be able to get the
scan result from the wdev. Change all dumps to unify the
code, but ones other than scan don't really support being
executed on a wdev that has no netdev.

mac80211: fix P2P-Device management frame RX
There's an issue in receiving broadcast management frames
on P2P Device virtual interfaces, such frames have the RX
flag IEEE80211_RX_RA_MATCH cleared and are thus dropped
in ieee80211_rx_h_mgmt_check(). They should be let through
to make it to ieee80211_rx_h_userspace_mgmt() and then to
userspace.

Bluetooth: Rename LE_SCANNING_* macros
This patch renames LE_SCANNING_ENABLED and LE_SCANNING_DISABLED
macros to LE_SCAN_ENABLE and LE_SCAN_DISABLE in order to keep
the same prefix others LE scan macros have.
It also fixes le_scan_enable_req function so it uses the LE_SCAN_
ENABLE macro instead of a magic number.

Bluetooth: Add macros for filter duplicates values
This patch adds macros for filter_duplicates parameter values from
HCI LE Set Scan Enable command. It also fixes le_scan_enable_req
function so it uses the LE_SCAN_FILTER_DUP_ENABLE macro instead of
a magic number.
The LE_SCAN_FILTER_DUP_DISABLE was also defined since it will be
required to properly support the GAP Observer Role.
