>Description:
	The bge driver allows to use jumbo frames by setting an MTU value
	of e.g. 8192. This works well in most cases. If NFS client and
	server are both capable to use jumbo frames, perfect! But clients
	with different adapters and standard MTUs can't access files on
	an NFS server if the latter one uses jumbo frames. Thus possible
	NFS problems should be mentioned in the man page.
>How-To-Repeat:
	Try to setup client and server as explained above.
