Network is not working with pfil module inserted

Hello

I have pfil 2.1.6 and ipf v4.1.8 installed on Solaris 8 108528-29 box.
I have empty rules and ipnat files and these entries in iu.ap file :

# cat /etc/opt/pfil/iu.ap
ce -1 0 pfil
hme -1 0 pfil
qfe -1 0 pfil
#

During OS boot following messages is logged in /var/messages/log file :

Apr 4 18:44:35 local@zinc krtld: [ID 151736 kern.notice]
/kernel/drv/sparcv9/pfil symbol
Apr 4 18:44:35 local@zinc krtld: [ID 197480 kern.notice] miocpullup
multiply defined

I have no problems with connection when pfil module is removed from NIC,
while with pfil module inserted into NIC network is not working :

# ifconfig ce700000 modlist
0 arp
1 ip
2 ce
# ping -s 192.168.200.1 1024 2

Can this problem be resolved somehow ?

I asked several times about VLAN tagged interface support. Got no reply.
Am I not polite enough or do not provide enough information ? Can you at
least tip me what should I do to get a response to my questions. Thanks
in advance.


With best regards
