From: Stefan Assmann <sassmann@xxxxxxxxx> [ Upstream commit 6ec12e1e9404acb27a7434220bbe5f75e7bb2859 ] When the virtual link state was set to "enable" ethtool would report link speed as 40000Mb/s regardless of the underlying device. Report the correct link speed. Example from a XXV710 NIC. Before: $ ip link set ens3f0 vf 0 state auto $ ethtool enp8s2 | grep Speed Speed: 25000Mb/s $ ip link set ens3f0 vf 0 state enable $ ethtool enp8s2 | grep Speed Speed: 40000Mb/s After: $ ip link set ens3f0 vf 0 state auto $ ethtool enp8s2 | grep Speed Speed: 25000Mb/s $ ip link set ens3f0 vf 0 state enable $ ethtool enp8s2 | grep Speed Speed: 25000Mb/s Signed-off-by: Stefan Assmann <sassmann@xxxxxxxxx> Tested-by: Aaron Brown <aaron.f.brown@xxxxxxxxx> Signed-off-by: Tony Nguyen <anthony.l.nguyen@xxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c index dd0c9604d3c92..bf2a1ae428610 100644 --- a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c +++ b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c @@ -58,7 +58,7 @@ static void i40e_vc_notify_vf_link_state(struct i40e_vf *vf) if (vf->link_forced) { pfe.event_data.link_event.link_status = vf->link_up; pfe.event_data.link_event.link_speed = - (vf->link_up ?
