This uses Octeon's asynchronous * IOBDMAs to issue IO accesses without stalling. Set this to zero * to disable this. Note that IOBDMAs require CVMSEG. * REUSE_SKBUFFS_WITHOUT_FREE * Allows the TX path to free an skbuff into the FPA hardware pool. This * can significantly improve performance for forwarding and bridging, but * may be somewhat dangerous. Checks are made, but if any buffer is reused * without the proper Linux cleanup, the networking stack may have very * bizarre bugs. */ #ifndef __ETHERNET_DEFINES_H__ #define __ETHERNET_DEFINES_H__ #include <asm/octeon/cvmx-config.h> #ifdef CONFIG_NETFILTER #define REUSE_SKBUFFS_WITHOUT_FREE 0 #else #define REUSE_SKBUFFS_WITHOUT_FREE 1 #endif #define USE_ASYNC_IOBDMA (CONFIG_CAVIUM_OCTEON_CVMSEG_SIZE > 0) /* Maximum number of SKBs to try to free per xmit packet. */ #define MAX_OUT_QUEUE_DEPTH 1000 #define FAU_TOTAL_TX_TO_CLEAN (CVMX_FAU_REG_END - sizeof(u32)) #define FAU_NUM_PACKET_BUFFERS_TO_FREE (FAU_TOTAL_TX_TO_CLEAN - sizeof(u32)) #define TOTAL_NUMBER_OF_PORTS (CVMX_PIP_NUM_INPUT_PORTS + 1) #endif /* __ETHERNET_DEFINES_H__ */Overall Contributors
