    net: hns3: pad the short frame before sending to the hardware

    BugLink: https://bugs.launchpad.net/bugs/1861090

    [ Upstream commit 36c67349a1a1c88b9cf11d7ca7762ababdb38867 ]

    The hardware can not handle short frames below or equal to 32
    bytes according to the hardware user manual, and it will trigger
    a RAS error when the frame's length is below 33 bytes.

    This patch pads the SKB when skb->len is below 33 bytes before
    sending it to hardware.
