Enable HW descriptor prefetch by default by setting plat->dma_cfg->dche = true in intel_mgbe_common_data(). Need to be noted that this capability only be supported in DWMAC core version 5.20 onwards. In stmmac, there is a checking to check the core version. If the core version is below 5.20, this capability wouldn`t be configured. Below is the iperf result comparison between HW descriptor prefetch disabled(DCHE=0b) and enabled(DCHE=1b). Tested on Intel Elkhartlake platform with DWMAC Core 5.20.

DWMAC Core 5.20 onwards supports HW descriptor prefetching. Additionally, it also depends on platform specific RTL configuration. This capability could be enabled by setting DMA_Mode bit-19 (DCHE). So, to enable this cability, platform must set plat->dma_cfg->dche = true and the DWMAC core version must be 5.20 onwards. Else, this capability wouldn`t be configured Signed-off-by:

Handling comm_channel_event in mlx4_master_comm_channel uses a double loop to determine which slaves have requested work. The search is always started at lowest slave. This leads to unfairness; lower VFs tends to be prioritized over higher VFs. The patch uses find_next_bit to determine which slaves to handle. Fairness is implemented by always starting at the next to the last start. An MPI program has been used to measure improvements. It runs 500 ibv_reg_mr, synchronizes with all other instances and then runs 500 ibv_dereg_mr. The results running 500 processes, time reported is for running 500 calls: ibv_reg_mr: Mod.

Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-04-22 This series contains updates to virtchnl header file, ice, and iavf drivers. Vignesh adds support to warn about potentially malicious VFs; those that are overflowing the mailbox for the ice driver. Michal adds support for an allowlist/denylist of VF commands based on supported capabilities for the ice driver. Brett adds support for iavf UDP segmentation offload by adding the capability bit to virtchnl, advertising support in the ice driver, and enabling it in the iavf driver. He also adds a helper function for getting the VF VSI for ice. Colin Ian King removes an unneeded pointer assignment. Qi enables support in the ice driver to support virtchnl requests from the iavf to configure its own RSS input set. This includes adding new capability bits, structures, and commands to virtchnl header file. Haiyue enables configuring RSS flow hash via ethtool to support TCP, UDP and SCTP protocols in iavf. ==================== Signed-off-by:

Attempt to detect malicious VFs and, if suspected, log the information but keep going to allow the user to take any desired actions. Potentially malicious VFs are identified by checking if the VFs are transmitting too many messages via the PF-VF mailbox which could cause an overflow of this channel resulting in denial of service. This is done by creating a snapshot or static capture of the mailbox buffer which can be traversed and in which the messages sent by VFs are tracked. Co-developed-by:
