Subject: net/ixgbe: fix flow control status
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c778b7a39f30ffbb8326f81389668dc5f6f30888;p=dpdk.git

net/ixgbe: fix flow control status

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")
