Subject: [dpdk-stable] [PATCH] net/ixgbe: delete MAC control frame fwd in struct adapter
Date: Fri, 22 May 2020 06:12:08 +0000
Message-ID: <20200522061208.31694-1-guinanx.sun@intel.com> (raw)

If some user set mac_ctrl_frame_fwd to 1 from fc ops,
then he do a port reset process of

testpmd> start
testpmd> set flow_ctrl mac_ctrl_frame_fwd on 0
testpmd> stop
testpmd> port stop 0
testpmd> port start 0
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.

In addition, add a value to mac_ctrl_frame_fwd in
the ixgbe_flow_ctrl_get () function.

Fixes: a524f550da6e ("net/ixgbe: fix flow control mode setting")
