如何使用 hxge.conf 文件设置参数

hxge 设备驱动程序配置文件位于以下目录中

/kernel/drv/hxge.conf

1. 通过取消注释 /kernel/drv/hxge.conf 文件中的相应行并提供新值来更改参数。

   以下是 /kernel/drv/hxge.conf 文件的内容。在此文件中列出并说明了所有参数。默认值在 hxge 驱动程序启动时装入。

   # cat /kernel/drv/hxge.conf
   #
   #
   # driver.conf file for Sun 10Gb Ethernet Driver (hxge)
   #
   #
   #------- Jumbo frame support ---------------------------------
   # To enable jumbo support,
   # accept-jumbo = 1;
   #
   # To disable jumbo support,
   # accept-jumbo = 0;
   #
   # Default is 0.
   #
   #
   #------- Receive DMA Configuration ----------------------------
   #
   # rxdma-intr-time
   #         Interrupts after this number of NIU hardware ticks have
   #         elapsed since the last packet was received.
   #         A value of zero means no time blanking (Default = 8).
   #
   # rxdma-intr-pkts
   #         Interrupt after this number of packets have arrived since
   #         the last packet was serviced. A value of zero indicates
   #         no packet blanking (Default = 0x20).
   #
   # Default Interrupt Blanking parameters.
   #
   # rxdma-intr-time = 0x8;
   # rxdma-intr-pkts = 0x20;
   #
   #
   #------- Classification and Load Distribution Configuration ------
   #
   # class-opt-****-***
   #         These variables define how each IP class is configured.
   #         Configuration options includes whether TCAM lookup
   #         is enabled and whether to discard packets of this class
   #
   #         supported classes:
   #         class-opt-ipv4-tcp class-opt-ipv4-udp class-opt-ipv4-sctp
   #         class-opt-ipv4-ah class-opt-ipv6-tcp class-opt-ipv6-udp
   #         class-opt-ipv6-sctp class-opt-ipv6-ah
   #         Configuration bits (The following bits will be decoded
   #         by the driver as hex format).
   #
   #
   #         0x10000:            TCAM lookup for this IP class
   #         0x20000:            Discard packets of this IP class
   #
   # class-opt-ipv4-tcp = 0x10000;
   # class-opt-ipv4-udp = 0x10000;
   # class-opt-ipv4-sctp = 0x10000;
   # class-opt-ipv4-ah = 0x10000;
   # class-opt-ipv6-tcp = 0x10000;
   # class-opt-ipv6-udp = 0x10000;
   # class-opt-ipv6-sctp = 0x10000;
   # class-opt-ipv6-ah = 0x10000;
   #
   #
   #------- FMA Capabilities ---------------------------------
   #
   # Change FMA capabilities to non-default
   #
   # DDI_FM_NOT_CAPABLE 0x00000000
   # DDI_FM_EREPORT_CAPABLE 0x00000001
   # DDI_FM_ACCCHK_CAPABLE 0x00000002
   # DDI_FM_DMACHK_CAPABLE 0x00000004
   # DDI_FM_ERRCB_CAPABLE 0x00000008
   #
   # fm-capable = 0xF;
   #
   # default is DDI_FM_EREPORT_CAPABLE | DDI_FM_ERRCB_CAPABLE = 0x5

   在以下示例中，NEM 丢弃此刀片系统的 TCP 通信。换句话说，hxge 驱动程序不会接收任何 TCP 通信。

   class-opt-ipv4-tcp = 0x20000;

   在以下示例中，将禁用 FMA 功能。

   fm-capable = 0x0;

2. 为了使新参数生效，请重新装入 hxge 驱动程序或重新引导系统。
