r8169: adjust the flow of hw_start
The suggestion as following: - initial settings or default settings - rtl_hw_start_xxx. rtl_hw_start_xxx may change some default settings. - enable tx/rx. This has to be after the above two steps. - rtl_set_rx_mode. AcceptXXXs have to be enabled after enabling tx/rx. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.
