[PATCH net 1/2] net: netcp: ethss: fix errors in ethtool ops

Show all headers | View raw

From: WingMan Kwok <w-kwok2@ti.com>

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.
