    i40e: add DCB and DCBNL support · 4e3b35b0
    Neerav Parikh 提交于
    This patch adds capability to configure DCB on i40e network
    interfaces using Intel XL710 adapter firmware APIs.
    
    By default all VSIs are only enabled for the default traffic
    class enabled by firmware for any given PF. The driver would
    query the firmware for the traffic classes that are enabled for
    the port and reconfigure the LAN VSI to match to the port traffic
    class settings. All other VSIs are only enabled for the default
    traffic class settings for now.
    
    The driver registers and listens to firmware events that may
    require change in the DCB settings. It may reconfigure the VSI
    settings based on these events.
    
    This patch exposes IEEE DCBNL interfaces for the i40e driver to
    allow any application to query the DCB settings on the adapter.
