Authentication issues on ethernet port

Hi

The behaviour of the Ethernet driver with VLAN configuration was updated in v7.7 M4 to fix problems like this.

Previously VLANs were disabled and the VLAN ID was set to be 0. If VLANs were enabled the packets would have been priority tagged (VLAN set to zero). This was quite legal but different behaviour to other Ethernet adapters.

This Intel behaviour is to have Priority and VLAN enabled, and the VLAN field set to zero, but still sent untagged traffic. When we changed our driver to have the same behaviour in 7.7 M4, it fixed these problems with 802.1x failures, as they could probably now enable VLANs and set the VLAN field in the same way is they did on an Intel adapter.

Are you still seeing problems with 7.7 M4?
