IEE(4)                     Kernel Interfaces Manual                     IEE(4)

NAME
     iee -- 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
     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 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
     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 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.
