71103bed42 AP: Add support for IPv4 neighbor entry management to the BSS bridge
This allows adding/deleting an IPv4 neighbor entry to/from the bridge,
to which the BSS belongs. This commit adds the needed functionality in
driver_nl80211.c for the Linux bridge implementation. In theory, this
could be shared with multiple Linux driver interfaces, but for now, only
the main nl80211 interface is supported.

This reverts commit 851b0c5581.

The kernel now has full support for this (and it is turned off
by default for hwsim) so wpa_supplicant should really go back
to autodetecting this so clients don't have to figure out what
to do.

Also add a debug message stating that P2P_DEVICE support is used.

01b3bbfc66 test: Remove driver_test.c
The driver_test.c driver wrapper (-Dtest in wpa_supplicant and
driver=test in hostapd) was previously used for testing without real
Wi-Fi hardware. mac80211_hwsim-based tests have practically replaced all
these needs and there has been no improvements or use for driver_test.c
in a long while. Because of this, there has not really been any effort
to maintain this older test tool and no justification to change this
either. Remove the obsoleted test mechanism to clean up the repository.

3e0272ca00 nl80211: Re-read MAC address on RTM_NEWLINK
Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.

Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.

b497a21267 nl80211: Ignore auth/assoc events when testing driver-SME
Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.

Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.
