> 
> The function i40e_vc_reset_vf attempts, up to 20 times, to handle a VF reset
> request, using the return value of i40e_reset_vf as an indicator of whether the
> reset was successfully triggered. Currently, i40e_reset_vf always returns true,
> which causes new reset requests to be ignored if a different VF reset is already in
> progress.
> 
> This patch updates the return value of i40e_reset_vf to reflect when another VF
> reset is in progress, allowing the caller to properly use the retry mechanism.
> 
> Fixes: 52424f974bc5 ("i40e: Fix VF hang when reset is triggered on another VF")
