2010-06-02ath5k: Stop queues only for NF calibrationBruno Randolf
As far as we know, only NF calibration interferes with RX/TX so we can leave the queues enabled for the other calibrations. BTW: Stopping the queues is not enough for avoiding transmissions, since there might be packets in the queue + beacons are also sent regularly! But i leave it like this until we have a better solution (stopping TX DMA?). Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2010-06-02ath5k: move noise floor calibration into taskletBruno Randolf
Seperate noise floor calibration from other PHY calibration and move it to the tasklet. This is the first step to more separation of different calibrations. Also move out ath5k_hw_request_rfgain_probe(ah) so we have one clean function for I/Q calibration on 5111x parts.

2010-06-02ath9k/debug: improve the snprintf() handlingDan Carpenter
The snprintf() function returns the number of bytes that *would* have been written (not counting the NULL terminator) and that can potentally be more than the size of the buffer. In this patch if there were one liners where string clearly fits into the buffer, then I changed snprintf to sprintf(). It's confusing to use the return value of snprintf() as a limitter without verifying that it's smaller than size. This is what initially caught my attention here. If we use the return value of sprintf() instead future code auditors will assume we've verified that it fits already. Also I did find some places where it made sense to use the return value after we've verified that it is smaller than the buffer size. Finally the read_file_rcstat() function added an explicit NULL terminator before calling snprintf(). That's unnecessary because snprintf() will add the null terminator automatically.

It only supports one hook per device because it makes no sense to do bridging and macvlan on the same device.

2010-06-02korina: fix deadlock on RX FIFO overrunPhil Sutter
By calling korina_restart(), the IRQ handler tries to disable the interrupt it's currently serving. This leads to a deadlock since disable_irq() waits for any running IRQ handlers to finish before returning. This patch addresses the issue by turning korina_restart() into a workqueue task, which is then scheduled when needed. Reproducing the deadlock is easily done using e.g. GNU netcat to send large amounts of UDP data to the host running this driver. Note that the same problem (and fix) applies to TX FIFO underruns, but apparently these are less easy to trigger. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: David S.
