Subject: [PATCH] ibmvnic: Fix IP offload control buffer

References: bsc#1076899
Patch-mainline: v4.15-rc9
Git-commit: f68979433deaa8a8a8b6396f944a0928a35713dc

Set some missing fields in the IP control offload buffer. This buffer is
used to enable checksum and TCP segmentation offload in the VNIC server.
The buffer length field and the checksum offloading bits were not set
properly, so fix that here.
