IEE(4) BSD Kernel Interfaces Manual IEE(4)NAMEiee — Intel i82596 10MBit/s Ethernet interface
SYNOPSIS
ews4800mips
iee* at sbdio?
hp700
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.
hp700
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 hp700 is done either manu‐
ally 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 faild 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 then 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 allo‐
cate 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 bussy=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.
