That was correct, yes.

Funny you should say that. Clearview UV integrated into ON about 15
minutes before you sent your message. ;-}

There's no notification in GLDv2, but the driver controls whether
VLANs are supported and can set up a separate entry point
(gldm_send_tagged) for the outbound tagged packets.
I don't think GLDv3 does it either, but it sounds like a reasonable
thing to add, if there's hardware that does this. The current code
just seems to be aware that some hardware can't do checksums in the
presence of VLAN headers.
