> for ADq on VF
> 
> This patch allocates number of queues requested by the user as a part of TC
> command when ADq is enabled on a VF.
> 
> In order to be consistent in design with PF implementation of ADq, don't
> allow to set channels via ethtool from VF when ADq is already enabled. This
> means the users will not be able to change the number of queues/channels
> via ethtool for a VF when ADq is ON. In order to be able to use set channels,
> users will be required to disable ADq first and then try setting the channels
> again.
> 
> When ADq is enabled on VF, it goes through a reset during which VSIs and
> queues are re-configured. Meanwhile if we receive link status message from
> PF even before the queues are re-configured, just ignore this link up
> message.
