The driver supports jumbo frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side Scaling (RSS) using MSI-X interrupts. .Pp The driver allocates 1 receive queue, transmit queue, event queue and IRQ per CPU up to a maximum of 64. IRQ affinities should be spread out using .Xr cpuset 1 . Interrupt moderation may be controlled through the sysctl .Va dev.sfxge.%d.int_mod (units are microseconds). .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Pp A large number of MAC, PHY and data path statistics are available under the sysctl .Va dev.sfxge.%d.stats . The adapter's VPD fields including its serial number are available under the sysctl .Va dev.sfxge.%d.vpd . .Sh HARDWARE The .Nm driver supports all 10Gb Ethernet adapters based on Solarflare SFC9000 family controllers. .Sh LOADER TUNABLES Tunables can be set at the .Xr loader 8 prompt before booting the kernel or stored in .Xr loader.conf 5 . Actual values can be obtained using .Xr sysctl 8 . .Bl -tag -width indent .It Va hw.sfxge.rx_ring The maximum number of descriptors in a receive queue ring. Supported values are: 512, 1024, 2048 and 4096. .It Va hw.sfxge.tx_ring The maximum number of descriptors in a transmit queue ring. Supported values are: 512, 1024, 2048 and 4096. .It Va hw.sfxge.tx_dpl_get_max The maximum length of the deferred packet .Dq get-list for queued transmit packets (TCP and non-TCP), used only if the transmit queue lock can be acquired. If a packet is dropped, the .Va tx_get_overflow counter is incremented and the local sender receives ENOBUFS. The value must be greater than 0. .It Va hw.sfxge.tx_dpl_get_non_tcp_max The maximum number of non-TCP packets in the deferred packet .Dq get-list , used only if the transmit queue lock can be acquired. If a packet is dropped, the .Va tx_get_non_tcp_overflow counter is incremented and the local sender receives ENOBUFS. The value must be greater than 0. .It Va hw.sfxge.tx_dpl_put_max The maximum length of the deferred packet .Dq put-list for queued transmit packets, used if the transmit queue lock cannot be acquired. If a packet is dropped, the .Va tx_put_overflow counter is incremented and the local sender receives ENOBUFS. The value must be greater than or equal to 0. .It Va hw.sfxge.tso_fw_assisted Enable/disable usage of FW-assisted TSO if supported by NIC firmware. Enabled by default. .It Va hw.sfxge.N.max_rss_channels The maximum number of allocated RSS channels for the Nth adapter. If set to 0 or unset, the number of channels is determined by the number of CPU cores. .It Va hw.sfxge.lro.table_size Size of the LRO hash table. Must be a power of 2. A larger table means we can accelerate a larger number of streams. .It Va hw.sfxge.lro.chain_max The maximum length of a hash chain. If chains get too long then the lookup time increases and may exceed the benefit of LRO. .It Va hw.sfxge.lro.idle_ticks The maximum time (in ticks) that a connection can be idle before it's LRO state is discarded. .It Va hw.sfxge.lro.slow_start_packets Number of packets with payload that must arrive in-order before a connection is eligible for LRO. The idea is we should avoid coalescing segments when the sender is in slow-start because reducing the ACK rate can damage performance. .It Va hw.sfxge.lro.loss_packets Number of packets with payload that must arrive in-order following loss before a connection is eligible for LRO. The idea is we should avoid coalescing segments when the sender is recovering from loss, because reducing the ACK rate can damage performance. +.It Va hw.sfxge.mcdi_logging +Enable logging of MCDI protocol messages (only available if enabled at compile-time). +.It Va hw.sfxge.N.mcdi_logging +Enable or disable logging of MCDI protocol messages on a per-port basis. The default for each +port will be the value of +.Va hw.sfxge.mcdi_logging. +The logging may also be enabled or disabled after the driver is loaded using the sysctl +.Va dev.sfxge.%d.mcdi_logging. .El .Sh SUPPORT For general information and support, go to the Solarflare support website at: .Pa https://support.solarflare.com . .Sh SEE ALSO .Xr arp 4 , .Xr netintro 4 , .Xr ng_ether 4 , .Xr vlan 4 , .Xr cpuset 1 , .Xr ifconfig 8 .Sh AUTHORS The .Nm driver was written by .An Philip Paeps and .An Solarflare Communications, Inc.
