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.
Responsible Changed From-To: freebsd-doc->jmg I'm going to take over this.. information that is general to to all ethernet cards supporting jumbo frames should not be in a card specific man page..
For bugs matching the following criteria: Status: In Progress Changed: (is less than) 2014-06-01 Reset to default assignee and clear in-progress tags. Mail being skipped
The problem is not bge-specific and it is not NFS-specific too as inconsistent MTU within a network is just beginner administrator's mistake.
