I spoke with HP today.  Their Procurve series switches support a maximum
of 1522 bytes to include 802.1Q tagging.  They wouldn't discuss if they
planned to join the rest of the world in supporting jumbo frames on GigE.

What is the largest MTU that you can use across a GigE fabric?

Frmo Extreme Networks manual:

The jumbo_frame_mtu range is 1523 to 9216. The value describes the maximum
size "on the wire," and includes 4 bytes of CRC plus another 4 bytes if
802.1Q tagging is being used.

I'd be surprised if other vendors are much different.
