We allocate them all at the same time, at startup. If they go missing,
we have more serious things to worry about, and the resulting oops will
be a perfectly acceptable result.

We're about to change semantics, leaving callers of
lbs_prepare_and_send_command() with the old broken priv->cur_cmd_retcode
crap. The existence of the callback command will be the trigger for the

This fixes Bug #9414 for b43legacy. This patch is the equivalent of one
submitted earlier for b43.
Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above and removes a couple of sparse warnings.

Multiple transmit fifo initialization -
- Assigned equal scheduling priority for all configured FIFO's.
- Modularized transmit traffic interrupt initialization since it is executed in
s2io_card_up and s2io_link. Enable continuous tx interrupt when link is UP
and vice verse.
- Enable transmit interrupts for all configured transmit fifos.
- Fixed typo errors.

Fixes to enable multiple transmit fifos (upto a maximum of eight).
- Moved single tx_lock from struct s2io_nic to struct fifo_info.
- Moved single ufo_in_band_v structure from struct s2io_nic to struct
fifo_info.
- Assign the respective interrupt number for the transmitting fifo in the
transmit descriptor (TXD).
- Added boundary checks for number of FIFOs enabled and FIFO length.

The bnx2x module depends on the zlib_inflate functions. The build will
fail if ZLIB_INFLATE has not been selected manually or by building another
module that automatically selects it.
Modify BNX2X config option to 'select ZLIB_INFLATE' like BNX2
and others. This seems to fix it.

Implement support for a SUN-specific PHY.
SUN provides a modified 82597-based board with their own
PHY that works with very little modification to the code. This

the same.

* misannotation: struct register_test members are actually host-endian
* bug: cpu_to_le64(n) >> 32 instead of cpu_to_le32(n >> 32) in setting
->bufhigh and similar for ->buflow (take low bits, _then_ convert to
little-endian, not the other way round).
* bug: setup_hw_rings() should not convert to little-endian at all (we
feed the result to writel(), not store in shared data structure), let
alone try to play with shifting and masking little-endian values. Introduced
when setup_hw_rings() went in, screwed both 64bit case and the old code for
32bit rings it had replaced.

This one is interesting - SBUS and PCI variants have
opposite endianness in descriptors (SBUS is sparc-only, so there
host-endian == big-endian).
Solution: declare a bitwise type (hme32) and in accessor
helpers do typechecking and force-casts (once we know that the
type is right).

* missing braces in !readl(...) & ...
* trivial endianness annotations
* in olympic_arb_cmd() the loop collecting fragments of
packet is b0rken on big-endian - we have
(next_ptr && (buf_ptr=olympic_priv->olympic_lap + ntohs(next_ptr)))
as condition and it should have swab16(), not ntohs() - it's host-endian
byteswapped, not big-endian. So if we get more than one fragment on big-endian
host, we get screwed.
This ntohs() got missed back when the rest of those had been switched
to swab16() in 2.4.0-test2-pre1 - at a guess, nobody had hit fragmented
packets during the testing of PPC fixes.
PS: Ken Aaker cc'd on assumption that he is the same guy who'd done the
original set of PPC fixes in olympic

We (ab)use priv->fw_ready to stop the worker thread from sending more
commands or data after the response to the HOST_SLEEP_ACTIVATE command
comes in. And we set it from the callback function _directly_ to ensure
that the worker thread sees it immediately; if we did it in
lbs_suspend() after waking up, that might be too late.
