- Kernel is NetBSD 1.5

Let me explain from the beginning:

I have built pseudo device driver which I have imported to the Kernel space
with modload
That basically fills ifnet structure and then does if_attach.

Once the module is loaded here is the  output from ifconfig -a and
netstat -rnalv as you requested:

Now, I insterted my module with "modload"

routing table didn't change but "ifconfig -a" did with only one entry:

bla0: flags=8800<SIMPLEX, MULTICAST> mtu 1500

Now I did the following set of operations:
1) ifconfig bla0 10.0.5.1 netmask 255.255.255.0
This changed the last entry in the "ifconfig -a" output to

bla0: flags=8800<SIMPLEX, MULTICAST> mtu 1500
        inet 10.0.5.1    netmask 0xffffff00

At the same time in the routing output is the following entry added:
Destination        Gateway            Flags     Refs     Use    Mtu
Interface
10.0.5/24          10.0.5.1              U           0        0         -
bla0

and now I could see the problem in /var/log/messages:
rtinit: wrong ifa (oxaaaaaa) was (oxbbbbbb)

Please advise...
