We always try to use skbuffs for packet buffers, so eliminate
a redundant define.

* A few defines are used to control the operation of this driver:
- * USE_SKBUFFS_IN_HW
- * Tells the driver to populate the packet buffers with kernel skbuffs.
- * This allows the driver to receive packets without copying them. It also
- * means that 32bit userspace can't access the packet buffers.
* USE_ASYNC_IOBDMA
* Use asynchronous IO access to hardware. This uses Octeon's asynchronous
* IOBDMAs to issue IO accesses without stalling. Set this to zero
