[net-next,v5,00/15,pull,request] 100GbE Intel Wired LAN Driver Updates 2020-08-24

This series introduces both the Intel Ethernet Common Module and the Intel
Data Plane Function.  The patches also incorporate extended features and
functionality added in the virtchnl.h file.
 
The format of the series flow is to add the data set, then introduce
function stubs and finally introduce pieces in large cohesive subjects or
functionality.  This is to allow for more in depth understanding and
review of the bigger picture as the series is reviewed.

Currently this is common layer (iecm) is initially only being used by only
the idpf driver (PF driver for SmartNIC).  However, the plan is to
eventually switch our iavf driver along with future drivers to use this
common module.  The hope is to better enable code sharing going forward as
well as support other developers writing drivers for our hardware

v2: Addresses comments from the original series.  This includes removing
    the iecm_ctlq_err in iecm_ctlq_api.h, the private flags and duplicated
    checks, and cleaning up the clamps in iecm_ethtool.c.  We also added
    the supported_coalesce_params flags in iecm_ethtool.c.  Finally, we
    got the headers cleaned up and addressed mismatching types from calls
    to cpu_to_le to match the types (this fixes C=2 W=1 errors that were
    reported).
v3: fixed missed compile warning/error with C=2 W=1
v4: Fixed missed static in idpf_main.c on idpf_probe. Added missing local
    variable in iecm_rx_can_reuse_page. Updated location of documentation,
    refactored soft reset path to take memory allocation into account,
    refactored ethtool stats to not use VA_ARGS, *greatly* reduced use of
    iecm_status enum, aligned use of periods in debug statements, and
    refactored to reduce line indents.
v5: Cleaned up some checks the core is already doing, corrected the
    calculation for txq and rxq, Removed the FW version that had been
    missed in previous version, dma_wmb call directly replacing a
    define to it, cleaned up the memory and header files that were not
    used, and cleaning up the self defining error codes.
