Reviewing the semaphore usage I noticed these down_interruptible calls. Most
of these aren't returning anything, so a caller can't tell if the operation
completed or not. prism54_wpa_bss_ie_get() returns zero, but it's treated as
the function failing which doesn't seem correct.

This turns out to be true only for rtl8180. On rtl8187, power levels are
indeed stored in nibbles, so this patch is wrong. Please revert this patch.

Stop byteswap-in-place in readBSSListRid(), annotate the sucker.
BTW, that had immediately found a bug - another codepath fetching
the same struct from card did _not_ byteswap, but used ->dBm the
same as everything else - host-endian. Fix in the next patch...

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.

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)).

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

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.

Currently, all non TAH equipped 4xx PPC's call emac_start_xmit() upon
xmit. This routine doesn't check if the frame length exceeds the max.
MAL buffer size.
This patch now changes the driver to call emac_start_xmit_sg() on all
GigE platforms and not only the TAH equipped ones (440GX). This enables
an MTU of 9000 instead 4080.
