    i40e: Update VEB's enabled_tc after reconfiguration · 23cd1f09
    Neerav Parikh authored
    When the port TC configuration changes as a result of DCBx the driver
    modifies the enabled TCs for the VEBs it manages. But, in the process
    it did not update the enabled_tc value that it caches on a per VEB basis.
    
    So, when the next reconfiguration event occurs where the number of TC
    value is same as the value cached in enabled_tc for a given VEB; driver
    does not modify it's TC configuration by calling appropriate AQ command
    believing it is running with the same configuration as requested.
    Now, as the VEB is not actually enabled for the TCs that are there any
    TC configuration command for VSI attached to that VEB with TCs that are
    not enabled for the VEB fails.
    
    This patch fixes this issue.
