NAME

f32 − Intel Ether Express Flash 32 Ethernet adapter

DESCRIPTION

The f32 interface provides STREAMS access to the Intel EE Flash 32 10 Mb Ethernet card. It uses IEEE 802.2 LLC class 1, llc driver. The f32 interface is an EISA-based, bus-master card.  It uses Intel’s 82596 chip. 

The /etc/conf/pack.d/f32/space.c file provides specific information for the operation of the board. The f32_no_tfd variable provides the maximum number of transmit frames that the driver will allow to be stored before the frames are processed.  The f32_no_tbd variable provides the maximum number of transmit buffers.  A transmit buffer is an area in memory that contains transmit data. It is currently set at 128 bytes per buffer. A frame can be linked with multiple buffers.  The f32_no_rfd variable provides the maximum number of receive frames.  The f32_no_rbd variable provides the maximum number of receive buffers. Typically, you should have more receive buffers than transmit buffers. 

f32watch_enable is a watch-dog timer variable.  Setting it to 1 enables the watchdog for transmit. If the transmit packet doesn’t return a transmit completion interrupt, a watch-dog timer will kick off and reset the controller.  Transmit and receive functions should then go back to normal.  f32watch_enable = 0 disables this feature.  It is recommended that you set f32watch_enable = 1. 

DIAGNOSTICS

Error messages and explanatory information:

"Intel EE Flash 32: No resources; up your f32/space.c f32_no_*"
The frames or buffers are running out on the f32 device driver.  You should increase your f32_no_* variables in /etc/conf/pack.d/f32/space.c. 

"Intel EE Flash 32: RAN OUT OF STREAMS dblock(##)"
Increase your STREAMS parameters. 

"Intel EE Flash32 Ethernet address x.x.x.x connector type: xxx"
This is a normal message at boot time. Possible connector types (xxx) are AUI (Auxiliary Unit Interface, D-shaped connector), BNC (Coaxial type connector), and TPE (Twisted Pair Ethernet, 10BaseT, which looks like a phone connector).
