- Since
kernel 2.6.32-358.xxxthe output of theethtoollooks strange on HP ProLiant hardware which uses Flex Fabric connectivity. I have seen this behavior on HP ProLiant G7 and HP ProLiant G8 systems. With kernel2.6.32-279.9.1.el6.x86_64the output ofethtoollooks as expected. - On Red Hat Enterprise Linux (RHEL) 6.4, why is the output of
ethtoolstrange when using it with abe2netnetwork card? - Why is my
ethtooloutput like this?
