bnx2 issue?

Hello gurus.
Please help me explain following problem.
I have IBM blade HS21 with SLES 9.3 and last vanilla kernel 2.6.21 (also 
trying from distro with similar problem).

ifconfig eth0 10.241.201.22 up
ping 10.241.200.10 - all is ok in this step

ifconfig eth0 0.0.0.0
vconfig add eth0 1
ifconfig vlan1 10.241.201.22 up

After that I have only one route through vlan1
ping 10.241.200.10 - destination host unreachable

What can be problem here? bnx2 module or 8021q? My Nortel configured 
with vlan 1.
While ping is running I can see that arp-replies didn't pass from eth0 
to vlan1.

tcpdump -ni eth0:
arp who-has 10.241.200.10 tell 10.241.201.22
arp reply 10.241.200.10 is-at ....
arp who-has 10.241.200.10 tell 10.241.201.22
arp reply 10.241.200.10 is-at ....

tcpdump -ni vlan1:
arp who-has 10.241.200.10 tell 10.241.201.22
arp who-has 10.241.200.10 tell 10.241.201.22
arp who-has 10.241.200.10 tell 10.241.201.22
...

I hope that my NIC is BCM5708S.
Iptables disabled, modules loaded, etc.

Any help would be highly appreciated.
