2021-10-11xhci: add quirk for host controllers that don't update endpoint DCSJonathan Bell3-2/+28
Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints at least, if the xHC halts on a particular TRB due to an error then the DCS field in the Out Endpoint Context maintained by the hardware is not updated with the current cycle state. Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit from the TRB that the xHC stopped on.

2021-10-10usb: chipidea: udc: make controller hardware endpoint primedPiyush Mehta1-0/+8
Root-cause: There is an issue like endpoint is not recognized as primed, when bus have more pressure and the add dTD tripwire semaphore (ATDTW bit in USBCMD register) that can cause the controller to ignore a dTD that is added to a primed endpoint. This issue observed with the Windows10 host machine. Workaround: The software must implement a periodic cycle, and check for each dTD, if the endpoint is primed. It can do this by reading the corresponding bits in the ENDPTPRIME and ENDPTSTAT registers. If these bits are read at 0, the software needs to re-prime the endpoint by writing 1 to the corresponding bit in the ENDPTPRIME register. Added conditional revision check of 2.20[CI_REVISION_22].

2021-10-10staging: vt6655: fix camelcase in ldBmThresholdTommaso Merciai3-26/+26
Replace camel case variable ldBmThreshold with snake case variable dbm_threshold. ldBmThreshold is in hungarian notation, where "l" is for long and "dbm" is for decibel-milliwatt (signal strenght). This variable contain's signal strenght threshold in dbm.

2021-10-10staging: vt6655: fix camelcase in bShortSlotTimeTommaso Merciai4-6/+6
Replace camel case variable bShortSlotTime with snake case variable short_slot_time. bShortSlotTime is a boolean variable, if true short slot time is enabled, false not. Short Slot Time reduces the slot time from 20 microseconds to 9 microseconds, where the slot time is the maximum theoretical time for a frame to travel a network.

2021-10-10octeontx2-pf: Simplify the receive buffer size calculationSubbaraya Sundeep6-28/+35
This patch separates the logic of configuring hardware maximum transmit frame size and receive frame size. This simplifies the logic to calculate receive buffer size and using cqe descriptor of different size. Also additional size of skb_shared_info structure is allocated for each receive buffer pointer given to hardware which is not necessary. Hence change the size calculation to remove the size of skb_shared_info. Add a check for array out of bounds while adding fragments to the network stack.

2021-10-10ethernet: Remove redundant 'flush_workqueue()' callsChristophe JAILLET12-15/+0
'destroy_workqueue()' already drains the queue before destroying it, so there is no need to flush it explicitly. Remove the redundant 'flush_workqueue()' calls. This was generated with coccinelle: @@ expression E; @@ - flush_workqueue(E); destroy_workqueue(E); Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> #mlx* Signed-off-by: David S.
