[dpdk-dev] [PATCH] ixgbevf: fix link status for PF up/down events

[Thomas Monjalon]

2015-06-16 15:38, Sergio Gonzalez Monroy:
> Current ixgbe VF base driver only really read the status register when:
>  - get_link_status is true
>  - link reset
>  - mailbox timeout.
> 
> We only set get_link_status to true when we start the PF/VF, so
> following calls to ixgbe_dev_link_update will just keep the old link
> status unless the link has been reset.
> 
> Because of this behaviour, when the link status of the PF changes after
> the VF has been initialized, we do not read the current status register
> from the nic and instead we just keep the old link status.
> 
> Fix the problem by setting this field to true before calling
> ixgbe_check_link function from base driver. We don't need to check after
> this call for get_link_status anymore, so remove it.
