[dpdk-dev] [PATCH v2] net/ixgbe: fix statistics error in flow control mode

[Guinan Sun <guinanx.sun@intel.com>]

The register autoneg can't be updated synchronously
with flow control mode setting in the state of port start
, so NIC statistics error occurs. AUTO_NEG Advt register
should be updated by ixgbe_setup_fc() when enabling flow control.
The patch fixes the issue.
