net: hns3: unify maybe_stop_tx for TSO and non-TSO case
Currently, maybe_stop_tx ops for TSO and non-TSO case share some BD
calculation code, so this patch unifies the maybe_stop_tx by removing
the maybe_stop_tx ops. skb_is_gso() can be used to differentiate the
case between TSO and non-TSO case if there is need to handle special
case for TSO case.
This patch also add tx_copy field in "ethtool --statistics" to help
better debug the performance issue caused by calling skb_copy.
