NAME
iee — Intel i82596 10MBit/s Ethernet interface
SYNOPSIS
ews4800mips
iee* at sbdio?
hppa
iee* at gsc?
DESCRIPTION
The
iee device provides access to the Intel i82596 10MBit/s Ethernet interface.
iee supports IEEE 802.1Q Virtual LANs.
iee operates the i82596 in 32-Bit Linear Mode, opposed to
ie(4) that drives the i82596 only in i82586 compatibility mode.
HARDWARE
ews4800mips
The iee interface supports Intel i82596CA based on-board Ethernet on EWS4800/350.
hppa
The iee interface supports Intel i82596DX on ASP/ASP2 based machines and the i82596CA macrocell in LASI based machines. GSC expansion cards may work, but are not tested. Media selection on hppa is done either manually via hardware jumper or automatically depending on machine model.
DIAGNOSTICS
-
iee%d: iee_intr: receive error %d, rfd_status=0x%.4x, rfd_count=0x%.4x.
-
An error during frame reception occurred. The frame was dropped.
-
iee%d: iee_intr: can't allocate mbuf.
-
-
iee%d: iee_intr: can't alloc mbuf cluster.
-
A frame was received, but dropped due to lack of memory.
-
iee%d: iee_intr: receive ring buffer overrun
-
Many frames where received under high load and the receive ring buffer was to small to store them all. Frame reception was restarted from scratch. Most likely there where frames lost.
-
iee%d: iee_intr: scb_status=0x%x scb_cmd=0x%x failed command %d: cb_status[%d]=0x%.4x cb_cmd[%d]=0x%.4x
-
A transmit or setup command was not executed successfully.
-
iee%d: iee_intr: crc_err=%d
-
Number of frames with a CRC error received.
-
iee%d: iee_intr: align_err=%d
-
Number of unaligned frames received.
-
iee%d: iee_intr: resource_err=%d
-
Number of good frames dropped because the receive ring buffer was full.
-
iee%d: iee_intr: overrun_err=%d
-
Number of frames lost because the system bus was not available for DMA.
-
iee%d: iee_intr: rcvcdt_err=%d
-
Number of collisions detected during frame reception.
-
iee%d: iee_intr: short_fr_err=%d
-
Number of frames received that where shorter than the minimum frame length.
-
iee%d: iee_start: failed to load DMA map
-
A mbuf(9) chain with too many elements could not be setup for transmission. The mbuf(9) chain will be merged into a single mbuf(9) cluster and retransmitted.
-
iee%d: iee_start: can't allocate mbuf.
-
-
iee%d: iee_start: can't load TX DMA map.
-
Said error occurred during merging the mbuf(9) chain into a mbuf(9) cluster. The frame was dropped.
-
iee%d: iee_init: can't create TX DMA map
-
-
iee%d: iee_init: can't allocate mbuf
-
-
iee%d: iee_init: can't allocate mbuf cluster
-
-
iee%d: iee_init: can't create RX DMA map
-
-
iee%d: iee_init: can't load RX DMA map
-
There was no memory free to allocate resources when the operator tried to bring the interface up. The interface will not come up. Try again later.
-
iee%d: iee_watchdog: transmit timeout %d
-
-
iee%d: iee_watchdog: setup timeout %d
-
The hardware didn't respond to a transmit or setup command within five seconds. The interface will be reset and restarted.
-
iee%d: iee_gsc_cmd: timeout n=%d
-
Timeout at sending a channel attention command to the chip.
-
iee%d: iee_gsc_reset timeout busy=0x%x
-
Timeout at resetting the chip. Possible errors during autoconf(4).
-
iee%d: iee_gsc_attach: can't map I/O space
-
The driver failed to map the I/O ports of the chip. The device will not be attached.
-
iee%d: iee_gsc_attach: can't allocate %d bytes of DMA memory
-
-
iee%d: iee_gsc_attach: can't map DMA memory
-
-
iee%d: iee_gsc_attach: can't create DMA map
-
-
iee%d: iee_gsc_attach: can't load DMA map
-
The driver failed to get the shared DMA memory for the chip. The device will not be attached.
HISTORY
The iee driver appeared in NetBSD 2.0.
