Subject: [dpdk-stable] [PATCH v2 2/2] net/ixgbe: fix flow control status get
Date: Sat, 23 May 2020 05:22:39 +0000
Message-ID: <20200523052239.62928-3-guinanx.sun@intel.com> (raw)
In-Reply-To: <20200523052239.62928-1-guinanx.sun@intel.com>

mac_ctrl_frame_fwd assignment is missing, so
setting mac_ctrl_frame_fwd should be added in
ixgbe_flow_ctrl_get().
The patch fixes the issue.

Fixes: 56ea46a997b7 ("ethdev: retrieve flow control configuration")
Cc: stable@dpdk.org
