/*
* A few defines are used to control the operation of this driver:
- * CONFIG_CAVIUM_RESERVE32
- * This kernel config options controls the amount of memory configured
- * in a wired TLB entry for all processes to share. If this is set, the
- * driver will use this memory instead of kernel memory for pools. This
- * allows 32bit userspace application to access the buffers, but also
- * requires all received packets to be copied.
- * 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_HW_TCPUDP_CHECKSUM
- * Controls if the Octeon TCP/UDP checksum engine is used for packet
- * output. If this is zero, the kernel will perform the checksum in
- * software.
* 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
