7698d6977a ray_cs fixes
bugs galore:
	* 0xf380 instead of htons(ETH_P_AARP), etc.  Works only on l-e.
	* back in 2.3.20 driver got readb() and friends instead of
direct dereferencing of iomem.  Somebody got too enthusiatic and replaced
	ntohs(p->mrx_overflow)
with
	ntohs(read(&p->mrx_overflow)
without noticing that (a) the sucker is 16bit and (b) that expression can't possibly
be portable anyway (hell, on l-e it's always less than 256, on b-e it's always a
multiple of 256).  Proper fix is
	swab16(readw(&p->mrx_overflow)
taking into account the conversion done by readw() itself.  That crap happened
in several places; the same fix applies.
	* untranslate() assumes little-endian almost everywhere, except for
the code checking for IPX/AARP packets; there we forgot ntohs(), so that part
only works on big-endian.

0300b3321d airo: bug in airo_interrupt() handling on incoming 802.11
On big-endian we end up with swapped first two bytes in packet,
due to earlier conversion to host-endian and forgotten conversion
back.

The code we calculated that host-endian for had been duplicated
several time - it finds the 802.11 MAC header length by the first
two bytes of packet; taken into a new helper (header_len(__le16 ctl)).

977b143c13 airo: fix transmit_802_11_packet()
a) gaplen would better be stored little-endian
b) for control packets (shorter than 24-byte header) we ended up with
        bap_write(ai, hdrlen == 30 ?
                (const u16*)&gap.gaplen : (const u16*)&gap, 38 - hdrlen, BAP1);
passing to card the data past the end of gap (i.e. random stuff from stack)
and did _not_ feed the gaplen at the right offset.
c) sending the contents of uninitialized fields of struct is Not Nice(tm) either

f12ca5f97b [MACVLAN]: Fix thinko in macvlan_transfer_operstate()
When the lower device's carrier is off, the macvlan devices's
carrier state should be checked to decide whether it needs to
be turned off. Currently the lower device's state is checked
a second time.

This still works, but unnecessarily tries to turn off the
carrier when its already off.

af30151709 [VLAN]: Simplify vlan unregistration
Keep track of the number of VLAN devices in a vlan group. This allows
to have the caller sense when the group is going to be destroyed and
stop using it, which in turn allows to remove the wrapper around
unregister_vlan_dev for the NETDEV_UNREGISTER notifier and avoid
iterating over all possible VLAN ids whenever a device in unregistered.

Also fix what looks like a use-after-free (but is actually safe since
we're holding the RTNL), the real_dev reference should not be dropped
while we still use it.
