Hi,
I hope you are the right receiver of 8021q-patches.
We are running SuSe 8.0, i.e kernel 2.4.18.

- When addding several egress-mappings we get stuck in an eternal
loop if they end up in the same hash-bucket, see vlan_dev.c.path.

- If we try to remove a vlan with VID 0, ifconfig stops working
completly.
We fixed it with vlan.c.patch.
