    net: hns3: change SSU's buffer allocation according to UM · 9e15be90
    Yunsheng Lin authored
    Currently when there is share buffer in the SSU(storage
    switching unit), the low waterline for RX private buffer is
    too low to keep the hardware running. Hardware may have
    processed all the packet stored in the private buffer of the
    low waterline before the new packet comes, because hardware
    only tell the peer send packet again when the private buffer
    is under the low waterline.
    
    So this patch only allocate RX private buffer if there is
    enough buffer according to hardware user manual.
    
    This patch also reserve some buffer for reusing when TC num
    is less than or equal to 2, and change PAUSE_TRANS_GAP &
    HCLGE_NON_DCB_ADDITIONAL_BUF according to hardware user
    manual.
