This * allows 32bit userspace application to access the buffers, but also * requires all received packets to be copied. - * CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS - * This kernel config option allows the user to control the number of - * packet and work queue buffers allocated by the driver. If this is zero, - * the driver uses the default from below. * 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_32BIT_SHARED - * This define tells the driver to allocate memory for buffers from the - * 32bit sahred region instead of the kernel memory space. * 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_MULTICORE_RECEIVE - * Process receive interrupts on multiple cores. This spreads the network - * load across the first 8 processors. If ths is zero, only one core - * processes incomming packets. * USE_ASYNC_IOBDMA * Use asynchronous IO access to hardware. This uses Octeon's asynchronous * IOBDMAs to issue IO accesses without stalling.
