  When the port starts, the hw register is reset first,
and then the required parameters are set again.
If the parameters to be used are not set after resetting the register,
a read register error will occur. This patch is used to fix the problem.

Fixes: af75078fece3 ("first public release")

Sure, this patch has added "Cc: stable@dpdk.org", so the LTS maintainer would
backport them to 19.11 and 18.11.

Hi, guinan

 In this patch, you have add a new parameter of mac_ctrl_frame_fwd, it should not be clear in ixgbe_dev_stop(),
Or it will be over write when do port reset, and also you should add mac_ctrl_frame_fwd in ixgbe_flow_ctrl_get() for FC info get.
Although this patch has been merged, please commit fix patch for it, thanks!

Hi，guinan

	More info for this problem:
If some user set mac_ctrl_frame_fwd to 1 from fc ops, then he do a port reset process of
"
1. testpmd> start
2. testpmd> set flow_ctrl mac_ctrl_frame_fwd on 0
3. testpmd> stop
4. testpmd> port stop 0
5. testpmd> port start 0
6. testpmd> start
"
Then after this process, the mac_ctrl_frame_fwd has been change to "off", 
so we should delete " adapter->mac_ctrl_frame_fwd = 0;" from dev-stop.
  
Another problem is "add mac_ctrl_frame_fwd in ixgbe_flow_ctrl_get() for FC info get", it is
Independent on the above one.

Then after this process, the mac_ctrl_frame_fwd has been change to "off", so we should delete " adapter->mac_ctrl_frame_fwd = 0;" from dev-stop. 
Another problem is "add mac_ctrl_frame_fwd in ixgbe_flow_ctrl_get() for FC info get", it is Independent on the above one.
