[c-nsp] Do WS-X6316-GE-TX blades support jumbo frames?

Does anyone know first-hand if the WS-X6316-GE-TX's support jumbos? The
6516-GE-TX's do, but I can't find anything explicit on the 6316's. I'm
assuming they don't because the rest of the 63xx line cards don't, but I
can't be sure. I appreciate any help.

*The default MTU size is 9216 bytes after you enable jumbo frame support on
the individual port. However, an Application Specific Integrated Circuit
(ASIC) limitation requires that you limit the MTU size to 8092 bytes on
these 10/100-based line cards:
WS-X6248-RJ-45
WS-X6248A-RJ-45
WS-X6248-TEL
WS-X6248A-TEL
WS-X6348-RJ-45
WS-X6348-RJ-45V
WS-X6348-RJ-21
The WS-X6516-GE-TX is also affected at 100 Mbps. At 10/1000 Mbps, up to 9216
bytes can be supported. However, the WS-X6548-RJ-45 line card is not
affected, as this line card uses newer ASICs.*
