Re: [HSSG] Topics for Consideration: Jumbo Frames
Since 802.3 has a speed agnostic MAC specification, wouldn't we want to keep it that way and therefore not make jumbo frames an HSSG specific work item?

Jumbo frames are great as long as you stay in the HS environment. A jumbo
frame hitting a 100baseT (or, heaven help us, a 10baseT) link will mess with
any QoS assumptions. Nasty things will happen bridging to non-Ethernet 802
LANs as well. I think this question needs to be addressed at a combo
802.1/802.3 level since it is a real architecture issue ...
