"remained_buf_len" has to be large enough to hold the value from "mgmt_ie_buf_len". That variable is type u32, but it only holds small values so I have changed to both variables to int. Also I removed the bogus initialization from "mgmt_ie_buf_len" so that GCC can detect if it is used unitialized. I moved the declaration of "remained_buf_len" closer to where it is used so it's easier to read.

This leads to CRC errors on high number of incoming packets and is not needed according to the datasheet. This patch fixes it by the following steps: 1) remove this reset in pch_gbe_stop_receive(), which causes some functions to not be used anywhere 2) remove already unused functions pch_gbe_wait_clr_bit_irq() and pch_gbe_mac_reset_rx() to correctly build 3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to pch_gbe_up() where it's only needed after we've removed the MAC_RX reset 4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx() to more precisely reflect what the functions are now doing. After these changes we already don't see the CRC errors and gain some increase in RX processing speed. Signed-off-by: Veaceslav Falico Signed-off-by: David S.

Patch fixes problem by adding .reset_resume calback, hence we do not unbind usb device on resume.

Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

The client will then answer using a normal Ack instead of a BlockAck. This acknowledgement has no TID stored and therefore the hardware is not able to provide us the corresponding TID. The TID set by the hardware in the tx status descriptor has to be seen as undefined and not as a valid TID value for normal acknowledgements. Doing otherwise results in a massive amount of retransmissions and stalls of connections. Users may experience low bandwidth and complete connection stalls in environments with transfers using multiple TIDs.

These devices can be handled by this driver with only a minor change to the probing logic, allowing a single combined control and data interface. This works because the devices - include a CDC Union descriptor labelling the combined interface as both master and slave, and - have an alternate setting #1 for the bulk endpoints on the combined interface. The 3G/LTE network connection is managed by vendor specific AT commands on a serial function in the same composite device. Handling the managment function is out of the scope of this driver.

This check has been added before the WORD_SWAP register is programmed, so we need to check for swapped register value as well. Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning checked with SMSC and wrote: The chip architects have concluded we should be reading PMT_CTRL until we see any of bits 0, 8, 16 or 24 set. Then we should read BYTE_TEST to check the byte order is correct (as we already do). The rationale behind this is that some of the chip variants have word order swapping features too, so the READY bit could actually be in any of the 4 possible locations. The architects have confirmed that if any of these 4 positions is set the chip is ready. The other 3 locations will either never be set or can only go high after READY does (so also indicate the device is ready). This change will check for the READY bit at the 16th position. We do not check the other two cases (bit 8 and 24) since the driver does not support byte-swapped register read/write. Signed-off-by: Kamlakant Patel Signed-off-by: David S.

When the mdio-gpio driver is probed via device trees, the platform device id is set as -1, However the pdev->id is re-used as bus-id for while creating mdio gpio bus. So For device tree case the mdio-gpio bus name appears as "gpio-ffffffff" where as for non-device tree case the bus name appears as "gpio-" Which means the bus_id is fixed in device tree case, so we can't have two mdio gpio buses via device trees. Assigning a logical bus number via device tree solves the problem and the bus name is much consistent with non-device tree bus name. Without this patch 1. we can't support two mdio-gpio buses via device trees. 2. we should always pass gpio-ffffffff as bus name to phy_connect, very different to non-device tree bus name. So, setting up the bus_id via aliases from device tree is the right solution and other drivers do similar thing. Signed-off-by: Srinivas Kandagatla Signed-off-by: David S.

Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq) This usage is wrong because the pending bit is cleared just before the work's fn is executed and if the function re-arms itself we might end up with the work still running. It's safe to call cancel_delayed_work_sync() even if the work is not queued at all. Observation 2: Use of INIT_DELAYED_WORK() Work needs to be initialized only once prior to (de/en)queueing. Observation 3: IFF_UP is set only after ndo_open is called Related race conditions: 1. Race between bonding_store_miimon() and bonding_store_arp_interval() Because of Obs.1 we can end up having both works enqueued. 2. Multiple races with INIT_DELAYED_WORK() Since the works are not protected by anything between INIT_DELAYED_WORK() and calls to (en/de)queue it is possible for races between the following functions: (races are also possible between the calls to INIT_DELAYED_WORK() and workqueue code) bonding_store_miimon() - bonding_store_arp_interval(), bond_close(), bond_open(), enqueued functions bonding_store_arp_interval() - bonding_store_miimon(), bond_close(), bond_open(), enqueued functions 3. By Obs.1 we need to change bond_cancel_all() Bugs 1 and 2 are fixed by moving all work initializations in bond_open which by Obs. 2 and Obs. 3 and the fact that we make sure that all works are cancelled in bond_close(), is guaranteed not to have any work enqueued. Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so they can't race with bond_close and bond_open. The opposing work is cancelled only if the IFF_UP flag is set and it is cancelled unconditionally. The opposing work is already cancelled if the interface is down so no need to cancel it again. This way we don't need new synchronizations for the bonding workqueue. These bugs (and fixes) are tied together and belong in the same patch. Note: I have left 1 line intentionally over 80 characters (84) because I didn't like how it looks broken down. If you'd prefer it otherwise, then simply break it. v2: Make description text < 75 columns Signed-off-by: Nikolay Aleksandrov Signed-off-by: Jay Vosburgh Signed-off-by: David S.
