| 41.Sh DESCRIPTION 42The 43.Nm 44driver provides support for PCI gigabit ethernet adapters based on 45the Alteon Networks Tigon gigabit ethernet controller chip. 46The Tigon 47contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and 48a PCI interface unit. --- 55 unchanged lines hidden (view full) --- 104.Pp 105Support for jumbo frames is provided via the interface MTU setting. 106Selecting an MTU larger than 1500 bytes with the 107.Xr ifconfig 8 108utility configures the adapter to receive and transmit jumbo frames. 109Using jumbo frames can greatly improve performance for certain tasks, 110such as file transfers and data streaming. 111.Pp | 43.Sh DESCRIPTION 44The 45.Nm 46driver provides support for PCI gigabit ethernet adapters based on 47the Alteon Networks Tigon gigabit ethernet controller chip. 48The Tigon 49contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and 50a PCI interface unit. --- 55 unchanged lines hidden (view full) --- 106.Pp 107Support for jumbo frames is provided via the interface MTU setting. 108Selecting an MTU larger than 1500 bytes with the 109.Xr ifconfig 8 110utility configures the adapter to receive and transmit jumbo frames. 111Using jumbo frames can greatly improve performance for certain tasks, 112such as file transfers and data streaming. 113.Pp |
| 114Header splitting support for Tigon 2 boards (this option has no effect for 115the Tigon 1) can be turned on with the 116.Dv TI_JUMBO_HDRSPLIT 117option. See 118.Xr zero_copy 9 119for more discussion on zero copy receive and header splitting. 120.Pp 121The 122.Nm 123driver normally uses jumbo receive buffers allocated by the 124.Xr jumbo 9 125buffer allocator, but can be configured to use its own private pool of 126jumbo buffers that are contiguous instead of buffers from the jumbo 127allocator, which are made up of multiple page sized chunks. To turn on 128private jumbos, use the 129.Dv TI_PRIVATE_JUMBOS 130option. 131.Pp |

| 188.Sh IOCTLS 189In addition to the standard 190.Xr socket 2 191.Xr ioctl 2 192calls implemented by most network drivers, the 193.Nm 194driver also includes a character device interface that can be used for 195additional diagnostics, configuration and debugging. With this character 196device interface, and a specially patched version of gdb, the user can 197debug firmware running on the Tigon board. 198.Pp 199These ioctls and their arguments are defined in the 200.Aq Pa sys/tiio.h 201header file. 202.Bl -tag -width ALT_WRITE_TG_MEM 203.It Dv TIIOCGETSTATS 204Return card statistics DMAed from the card into kernel memory approximately 205every 2 seconds. (That time interval can be changed via the 206.Dv TIIOCSETPARAMS 207ioctl.) The argument is 208.Va struct ti_stats . 209.It Dv TIIOCGETPARAMS 210Get various performance-related firmware parameters that largely affect how 211interrupts are coalesced.

The argument is 223.Va struct ti_trace_buf . 224.It Dv ALT_ATTACH 225This ioctl is used for compatibility with Alteon's Solaris driver. They 226apparantly only have one character interface for debugging, so they have 227to tell it which Tigon instance they want to debug. This ioctl is a noop 228for FreeBSD. 229.It Dv ALT_READ_TG_MEM 230Read the requested memory region from the Tigon board.
