As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187
USB stick, or unloading the driver rtl8187 using rmmod will cause a
kernel oops. There are at least two forms of the failure, (1) BUG:
Scheduling while atomic, and (2) a fatal kernel page fault. This
problem is reported in Bugzilla #14539.
This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2,
thus it is technically a regression; however, bisection did not locate
any faulty patch. The fix was found by comparing the faulty code in
rtl8187 with p54usb. My interpretation is that the handling of work
queues in mac80211 changed enough to the LEDs to be unregistered
before tasks on the work queues are cancelled. Previously, these
actions could be done in either order.
(Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the
code is the same in 2.6.31, so this may be a candidate for 2.6.31.x.

Since each firmware block takes on the order of several hundred usec
to upload to the hardware, using msleep in the inner loop would make
the firmware loading process take a lot more time than just doing
busy-waiting like we do now. But if we keep the busy-waiting, we can
at least add a cond_resched() to the inner loop so that we give other

When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS
filter so that we'll only see packets destined for our BSS. But if no
STA interfaces have been configured, we would end up passing the BSSID
00:00:00:00:00:00 into the POST_SCAN command, which actually disables
the hardware's BSS filter, as it's not a valid BSSID.
Fix this by passing in 01:00:00:00:00:00 instead (the criterion is
that the OUI part of the BSSID must be nonzero), and add comments to
explain what PRE_SCAN and POST_SCAN do.

mwl8k's ->prepare_multicast() currently just enables reception of
all multicast packets, which is somewhat ineffective.
Fix this by either disabling all multicast RX, enabling multicast
RX according to the multicast address filter table, or enabling all
multicast RX, depending on whether ->prepare_multicast() was given
any multicast addresses and whether the hardware multicast address
filter table is large enough to fit all requested addresses.

Minor changes to the transmit quiescing logic:
- Clarify the locking rules for ->tx_wait: only the holder of fw_mutex
can wait for the TX path to become idle, but tx_wait itself is read
and cleared by the TX reclaim tasklet under tx_lock.
- Inline mwl8k_txq_busy() in its callers.
- There's no need to kick the transmitter again in
mwl8k_tx_wait_empty(), since it will have been kicked when the
packets currently in the TX ring were added to it.
- If the TX ring didn't drain in time, run mwl8k_scan_tx_ring() after
reading priv->pending_pkts without dropping tx_lock in between.

Use offsetof instead of explicit implementation.
* fixes bug with omitted & like:
len = (byte)(((T30_INFO *) 0)->station_id + 20)
* avoids compiler warnings with wrong sizes (pointer-to-char cast):
len = (byte)(&(((T30_INFO *) 0)->universal_6));
* cleans up the code

The current code probably returns -EINVAL a lot. Otherwise it would oops.
Compile tested only. Found by smatch (http://repo.or.cz/w/smatch.git).

drivers/net/bnx2.c: In function ‘bnx2_enable_forced_2g5’:

One fix would be to have an initial value, but a plain return might be better.

Since the kernel api already has the macro "min",
just use it instead of declaring another one.

`ulp_type' is signed, make sure it is not negative
when we read the array element.

Fix inverted setting of 'retries'; when we are in the probe() path, we
should retry to enable the function only once; otherwise until it
times out.

The function was always setting the return value to the amount of
bytes transferred, overwriting the error code in error paths.

When the device stalls, clear it and retry; if it keeps failing too
often, reset the device.
This specially happens when running on virtual machines; the real
hardware doesn't seem to trip on stalls too much, except for a few
reports in the mailing list (still to be confirmed this is the cause,
although it seems likely.
NOTE: it is not clear if the URB has to be resubmitted fully or start
only at the offset of the first transaction sent. Can't find
documentation to clarify one end or the other.
Tests that just resubmit the whole URB seemed to work in my
environment.
