net: hns3: add support to set/get tx copybreak buf size via ethtool for hns3 driver
Tx copybreak buf size is used for tx copybreak feature, the feature is
used for small size packet or frag. It adds a queue based tx shared
bounce buffer to memcpy the small packet when the len of xmitted skb is
below tx_copybreak(value to distinguish small size and normal size),
and reduce the overhead of dma map and unmap when IOMMU is on.
Support setting it via ethtool --set-tunable parameter and getting
it via ethtool --get-tunable parameter.
