vmxnet3: set carrier state properly on probe
vmxnet3 fails to set netif_carrier_off on probe, meaning that when an interface is opened the __LINK_STATE_NOCARRIER bit is already cleared, and so /sys/class/net/<ifname>/operstate remains in the unknown state. Correct this by setting netif_carrier_off on probe, like other drivers do. Also, while we're at it, lets remove the netif_carrier_ok checks from the link_state_update function, as that check is atomically contained within the netif_carrier_[on|off] functions anyway Tested successfully by myself Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: "David S.
