Pause parameters include source address, transmit gap and pause time.
The default value of the pause source address is zero in the hardware.
Default pause parameters need to be set to the hardware. Also, when
setting new mac address, the pause source address need to be updated.

When setting MTU, actually what we do is configuring the max frame size
for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be
considered. And the frame size which is less than the default value
should not be set to the hardware. Because in the hardware, the the max
frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.

This patch fixes the bug setting a error max frame size to hardware.

commit a9c782822166 ("net: hns3: add support for set_pauseparam")
adds set_pauseparam support for ethtool cmd, but forgets to update
fc_mode_last_time when PFC mode is disabled in hclge_cfg_pauseparam().
The wrong fc_mode_last_time will be used to update flow control mode
when lldpad has been running. As a result, when using the ethtool
command "-a", user will get a wrong pause parameter.

This patch adds the fc_mode_last_time update when PFC mode is disabled.
