Most wireless drivers load their firmware at interface open time, which
generally occurs after the filesystem is available. However, the ipw drivers
load their firmware at probe time because firmware is required to read the
device MAC address. When built-in, probe happens before the filesystem is
available, hence device init will only complete successfully if the user
has made special arrangements (including firmware plus a loader in the
initramfs).

Note all this in the kconfig help text for both drivers.

We must not clear the FIF_BCN_PRBRESP_PROMISC bit in the
new_flags. The zd-driver does support sending beacons and
probe responses to the host. What the flag does is say "Send me
all beacons and probe responses". And we actually do that. We always
do that, so we ignore the case when the bit is disabled. But that is
fine. But we must not clear the flag, as that tells mac80211 that
we do not support passing beacons and probe responses to the stack.
And that's not true.

enable IBSS cell merging. if an IBSS beacon with the same channel, same ESSID
and a TSF higher than the local TSF (mactime) is received, we have to join its
BSSID. while this might not be immediately apparent from reading the 802.11
standard it is compliant and necessary to make IBSS mode functional in many
cases. most drivers have a similar behaviour.

* move the relevant code section (previously only containing debug code) down
to the end of the function, so we can reuse the bss structure.

* we have to compare the mactime (TSF at the time of packet receive) rather
than the current TSF. since mactime is defined as the time the first data
symbol arrived we add the time until byte 24 where the timestamp resides, since
this is how the beacon timestamp is defined. as some some drivers are not able
to give a reliable mactime we fall back to use the current TSF, which will be
enough to catch most (but not all) cases where an IBSS merge is necessary.

* in IBSS mode we want to allow beacons to override probe response info so we
can correctly do merges.

* we don't only configure beacons based on scan results, so change that
message.

* to enable this we have to let all beacons thru in IBSS mode, even if they
have a different BSSID.

define mactime as the time when the first data symbol arrived at the HW. the
old definition was questionable because 802.11 defines timestamp only for
beacon and probe response frames, and there it means the timestamp field.

a stricter definition of mactime is necessary for correct merging of IBSS.

note that it is up to the driver to convert whatever its hardware returns to
this definition. unfortunately we don't know for example when atheros hardware
takes its rx timestamp exactly :(
