I'm having a problem with VLANs. Outgoing packets are tagged correctly
and devices on the VLAN are responding. Unfortunately all of the
response packets stay on the raw device and are not allocated to the VLAN.

I've done some investigation (printks etc.), and have found that neither
of the following cases in sky2_status_intr() are being triggered...

                case OP_RXVLAN:
                        printk("RXVLAN, length=%u, status=%u\n", length,
status);
                        sky2->rx_tag = length;
                        break;

                case OP_RXCHKSVLAN:
                        printk("RXCHKSVLAN, length=%u, status=%u\n",
length, status);
                        sky2->rx_tag = length;
                        /* fall through */

... however the status when calling sky2_skb_rx() does have GMR_FS_VLAN
set, it's just we haven't been able to find out which VLAN the packet
comes from (and sky2->rx_tag is zero). Does anyone have any suggestions
as to how I proceed from here? I'm happy to test patches etc.

Did it work with older kernels?
