So, even we let VF sending Tx, it does not make sense at all. As my understanding, Flow control is used for full-duplex point-to-point connections. How about VF? What is its peer for the point-to-point connect? So if we enable it, it will be a security risk if attacker sends FC on VFs. Thanks Jingjing
