While setting up the ring parameters using ethtool the driver can panic or leak memory as ixgbe_open tries to setup tx & rx resources. The updated logic will use ixgbe_down/up after successful allocation of tx & rx resources Signed-off-by: Mallikarjuna R Chilakala <mallikarjuna.chilakala@intel.com> Signed-off-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> CC: stable@kernel.org Signed-off-by: David S.
