Fore PCA-200E HARP configuration problem

[Tim Lewis <timglewis@xxxxxxxxxxxx>]

Hi,

I am trying to use a FORE PCA-200E atm adapter for
packet analysis (tcpdump, libpcap etc).

My server is running FreeBSD 4.3-RELEASE connected via
a netoptics tap.  The tap attachment allows me to
receive data only (no Tx to the tap).  The tap is
attached between two Cisco routers.

I have configured the HARP software for SIGPVC
signalling.  Below is the output from the
configuration.

-----
# atm show config
Intf      Vendor    Model     Media   Bus  Serial No
hfa0      Fore      PCA-200E  OC-3c   PCI  41170
    MAC address = 00:20:48:40:a0:d2
    Hardware version = 2.0.1
    Firmware version = 3.0.1

# atm show interface
Interface  Sigmgr   State
hfa0       SIGPVC   ACTIVE
    ATM address = -
    Network interfaces: atm0

# atm show netif
Net Intf  Phy Intf  IP Address
atm0      hfa0      -

# atm show vcc
# atm show ipvcc

# atm add pvc hfa0 0 32 aal5 snap ip atm0 10.0.0.1
atm: ATM network is inoperable

-----

I have included all the appropriate atm support for
harp and the fore cards.  I have set the atm
configuration options from /etc/rc.conf as well as
setting them manually.

According to the source for /sbin/atm, the error is an
ENETDOWN from a call to ioctl.

I am not sure whether this error is from a
configuration problem on my behalf or if it is because
I have only one half of the link (Rx) connected.

I have applied a patch as described in PR kern/21790
which patched <src>/sys/dev/hfa/fore.h and
<src>/sys/dev/hfa/fore_receive.c with no success.

Any assistance with this problem would be most
appreciated.
