I really think this function should just return the number of bytes and
let the caller round it up to any boundary requirements it might have.

Might as well be specific here and call this a signed long.
Tab/spacing issue here as well.

Some versions of the Virtual I/O Server on Power
return 0x99 in the non-SCSI error status field as success,
rather than 0. This fixes the ibmvscsi driver to treat this
response as success.

Removes the use of bitfields from the ibmveth driver. This results
in slightly smaller object code.

Removes dead frag processing code from ibmveth. Since NETIF_F_SG was
not set, this code was never executed. Also, since the ibmveth
interface can only handle 6 fragments, core networking code would need
to be modified in order to efficiently enable this support.
