The iwm(4) iwm_poll_bit() function returns 1 on success, and 0 on failure,
whereas the iwl_poll_bit() in Linux iwlwifi returns < 0 on failure.
So the (ret < 0) check ended up ignoring any error returned by
iwm_poll_bit().

The wantresp field in struct iwm_rx_data has never been used for anything,
so we can just delete it.
Apparently struct iwm_sf_cfg_cmd was compiled correctly (using a 32bit
value to represent the enum), but it still seems like a very bad idea to use
an enum type in a __packed struct.

* hard code a noise floor of -96 for now. The noise floor update code returns
some "interesting" values that I can't map to anything useful right now.
* Ensure a default noise floor is set - otherwise the initial scan results
have a noise floor of '0'.
* Fix up the RSSI calculation to be correctly relative to the noise floor.
The RSSI routines return an absolute value in dBm - so fix this up.
* Cap RSSI values appropriately.
* Ensure we pass in a 1/2 dB unit value in to net80211.
Tested:
* Intel 7260, STA mode

In r304870, refcount handling was lifted out into a common OTP/SPROM code
path, but the refcount assertions in chipc_disable_sprom_pins() were not
updated accordingly; this triggered an assertion on BCM4331 devices when
releasing a SPROM pin reservation.

When mlx5e_sq_xmit() returns an error code and the mbuf pointer is set,
we should not free the mbuf, because the caller will keep the mbuf in
the drbr. Make sure the mbuf pointer is correctly set upon function

The hardware MTU size can't be set to a value less than 1500 bytes due
to side-band management support. Allow setting the software MTU size
below 1500 bytes, thus creating a mismatch between hardware and

This change also reduces the size of the mlx5e_sq structure so that the last

mutexes or using any callouts when active.
Trying to lock a mutex when KDB is active or the scheduler is stopped
can result in infinite wait loops. The same goes for calling callout
related functions which in turn lock mutexes.
If the USB controller at which a USB keyboard is connected is idle
when KDB is entered, polling the USB keyboard via USB will always
succeed. Else polling may fail depending on which state the USB
subsystem and USB interrupt handler is in. This is unavoidable unless
KDB can wait for USB interrupt threads to complete before stalling the
CPU(s).
