Subject: [net-next 06/11] ixgbe: FCoE: Add support for ndo_get_fcoe_hbainfo() call
From: Neerav Parikh <Neerav.Parikh@...el.com>
This patch implements support for ndo_get_fcoe_hbainfo()
call in the ixgbe driver.
This function will be called by the FCoE protocol stack to
obtain device specific information from the underlying
device configured to do FCoE.
