X-Git-Tag: v4.10-rc1~36^2~9

net: netcp: ethss: fix errors in ethtool ops

In ethtool ops, it needs to retrieve the corresponding
ethss module (gbe or xgbe) from the net_device structure.
Prior to this patch, the retrieving procedure only
checks for the gbe module.  This patch fixes the issue
by checking the xgbe module if the net_device structure
does not correspond to the gbe module.
