net: hns: fix wrong head when modify the tx feature when sending packets

Browse source

[ Upstream commit 84757d0839 ]

Upon changing the tx feature, the hns driver will modify the
maybe_stop_tx() and fill_desc() functions, if the modify happens
during packet sending, will cause the hardware and software
pointers do not match, and the port can not work anymore.

This patch deletes the maybe_stop_tx() and fill_desc() functions
modification when setting tx feature, and use the skb_is_gro()
to determine which functions to use in the tx path.
