2011-01-19bnx2x: Common init will be executed only once after PORYaniv Rosner1-0/+11
Common init used to be called by the driver when the first port comes up, mainly to reset and reload external PHY microcode. However, in case management driver is active on the other port, traffic would halted. So limit the common init to be done only once after POR.

2011-01-18ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan1-5/+5
The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).

There is an interoperability with AR9382/AR9380 in L1 state with a few root complexes which can cause a hang. This is fixed by setting some work around bits on the PCIE PHY.

2011-01-16qeth: postpone open till recovery is finishedUrsula Braun2-4/+32
The open function of qeth is not executed if the qeth device is in state DOWN or HARDSETUP. A recovery switches from state SOFTSETUP to HARDSETUP to DOWN to HARDSETUP and back to SOFTSETUP. If open and recover are running concurrently, open fails if it hits the states HARDSETUP or DOWN. This patch inserts waiting for recovery finish in the qeth open functions to enable successful qeth device opening in spite of a running recovery.

2011-01-14GRETH: resolve SMP issues and other problemsDaniel Hellstrom1-67/+92
Fixes the following: 1. POLL should not enable IRQ when work is not completed 2. No locking between TX descriptor cleaning and XMIT descriptor handling 3. No locking between RX POLL and XMIT modifying control register 4. Since TX cleaning (called from POLL) is running in parallel with XMIT unnecessary locking is needed. 5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is temporarily disabled (in POLL), and when IRQ is shared. 6. IRQ handler clears IRQ status, which is unnecessary 7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1 descriptors were available after a SKB been scheduled by XMIT. Instead the TX queue is stopped first when not enough descriptors are available upon entering XMIT. It was hard to split up this patch in smaller pieces since all are tied together somehow. Note the RX flag used in the interrupt handler does not signal that interrupt was asserted, but that a frame was received. Same goes for TX. Also, IRQ is not asserted when the RX flag is set before enabling IRQ enable until a new frame is received. So extra care must be taken to avoid enabling IRQ and all descriptors are already used, hence dead lock will upon us. See new POLL implementation that enableds IRQ then look at the RX flag to determine if one or more IRQs may have been missed. TX/RX flags are cleared before handling previously enabled descriptors, this ensures that the RX/TX flags are valid when determining if IRQ should be turned on again. By moving TX cleaning from POLL to XMIT in the standard case, removes some locking trouble. Enabling TX cleaning from poll only when not enough TX descriptors are available is safe because the TX queue is at the same time stopped, thus XMIT will not be called. The TX queue is woken up again when enough descriptrs are available. TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will not be enabled until XMIT must wait for free descriptors. Locking RX and XMIT parts of the driver from each other is needed because the RX/TX enable bits share the same register. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S.

The firmware agent is not available during resume. Loading the firmware during open() (see eee3a96c6368f47df8df5bd4ed1843600652b337) is not enough. close() is run during resume through rtl8169_reset_task(), whence the mildly natural release of firmware in the driver removal method instead.

uninitialized variable. skb_clone() dynamically allocates memory and may fail. If it does it returns NULL. This means we'll dereference a NULL pointer in drivers/net/usb/cdc_ncm.c::cdc_ncm_rx_fixup(). As far as I can tell, the proper way to deal with this is simply to goto the error label. Furthermore gcc complains that 'skb' may be used uninitialized: drivers/net/usb/cdc_ncm.c: In function ‘cdc_ncm_rx_fixup’: drivers/net/usb/cdc_ncm.c:922:18: warning: ‘skb’ may be used uninitialized in this function and I believe it is right. On the line where we pr_debug("invalid frame detected (ignored)" ... we are using the local variable 'skb' but nothing has ever been assigned to that variable yet.
