[PATCH] s390: qeth bug fixes
[patch 7/10] s390: qeth bug fixes.
From: Frank Pavlic <pavlic@de.ibm.com>
qeth network driver changes:
- Removed redundant code, use the same qeth_fill_buffer_frag
for TSO path either
- Using skb->frags solely is not correct since skb->data still
points to the beginning of the whole data, even when it is
a small portion we have to fill the qdio buffer with it.
