Enable DWMAC HW descriptor prefetch

This patch series to add setting for HW descriptor prefetch for DWMAC
version 5.20 onwards. For Intel platform, enable the capability by
default.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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. Observed line rate performance
improvement with HW descriptor prefetch enabled.

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

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.

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.

another sub-module was added to the enetc driver:

ERROR: modpost: "enetc_ierb_register_pf" [drivers/net/ethernet/freescale/enetc/fsl-enetc.ko] undefined!

The problem is that the enetc Makefile is not actually used for
the ierb module if that is the only built-in driver in there
and everything else is a loadable module.

Fix it by always entering the directory this time, regardless
of which symbols are configured. This should reliably fix the

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.

CN10K CPT coprocessor includes a component named RXC which
is responsible for reassembly of inner IP packets. RXC has
the feature to evict oldest entries based on age/threshold.
This patch adds a new mailbox to configure reassembly age
