2022-03-05bnxt_en: add an nvm test for hw diagnoseVikas Gupta4-18/+113
Add an NVM test function for devlink hw reporter. In this function an NVM VPD area is read followed by a write. Test result is cached and if it is successful then the next test can be conducted only after HW_RETEST_MIN_TIME to avoid frequent writes to the NVM.

2022-03-05bnxt_en: Eliminate unintended link toggle during FW resetMichael Chan1-3/+1
If the flow control settings have been changed, a subsequent FW reset may cause the ethernet link to toggle unnecessarily. This link toggle will increase the down time by a few seconds. The problem is caused by bnxt_update_phy_setting() detecting a false mismatch in the flow control settings between the stored software settings and the current FW settings after the FW reset. This mismatch is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG bit should not be added to link_info->req_flow_ctrl.

2022-03-05net: axienet: fix RX ring refill allocation failure handlingRobert Hancock1-30/+42
If a memory allocation error occurred during an attempt to refill a slot in the RX ring after the packet was received, the hardware tail pointer would still have been updated to point to or past the slot which remained marked as previously completed. This would likely result in the DMA engine raising an error when it eventually tried to use that slot again. If a slot cannot be refilled, then just stop processing and do not move the tail pointer past it. On the next attempt, we should skip receiving the packet from the empty slot and just try to refill it again. This failure mode has not actually been observed, but was found as part of other driver updates.

There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek chipset like MT7921 , MT7922 devices and future devices.

2022-03-04net: ethernet: sun: Remove redundant codeJiapeng Chong1-16/+0
Since the starting value in the for loop is greater than or equal to 1, the restriction is CAS_FLAG_REG_PLUS is in the file cassini.h is defined as 0x1 by macro, and the for loop and if condition is not satisfied, so the code here is redundant. Clean up the following smatch warning: drivers/net/ethernet/sun/cassini.c:3513 cas_start_dma() warn: we never enter this loop. drivers/net/ethernet/sun/cassini.c:1239 cas_init_rx_dma() warn: we never enter this loop. drivers/net/ethernet/sun/cassini.c:1247 cas_init_rx_dma() warn: we never enter this loop.

2022-03-04nfp: xsk: add AF_XDP zero-copy Rx and Tx supportNiklas Söderlund6-28/+756
This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so by adding a separate NAPI poll function that is attached to a each channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and restored when the XSK socket is terminated, this is done per channel. Support for XDP_TX is implemented and the XDP buffer can safely be moved from the Rx to the Tx queue and correctly freed and returned to the XSK pool once it's transmitted. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack. This patch is based on previous work by Jakub Kicinski. Signed-off-by: Niklas Söderlund <[email protected]> Signed-off-by: Simon Horman <[email protected]> Signed-off-by: David S.
