>Description:
The manpage for the vge driver says: "The jumbo frame support can be enabled by setting the interface MTU to any value larger than the default of 1500 bytes, up to a maximum of 9000 bytes."

However, this was disabled at least for some models with r200759.
>How-To-Repeat:
-
>Fix:
Update the manpage.

 Log:
   Mention that jumbo frame support is disabled on PCIe VT6130/VT6132
   controllers because of TX MAC hangs when trying to send a frame
   that is larger than 4K (see r200759).
