[Xen-users] Setting vifX.Y's MTU automatically in Xen 3

Hi all,

  I've got Xen 3.0 (stock as available on CentOS 5.6). I'm trying to use
jumbo frames, but when Xen creates vifX.Y interfaces, it uses 1500. This
brings the xenbrX bridges down to 1500, and effectively messes up
anything thinking that it can use the larger packet size.

  So how can I make sure that all vifX.Y interfaces created by Xen are
set to a given MTU? I've grepped the files under /etc/xen, but haven't
seen a specific place to set it.
