Subject[patch 110/149] Documentation/3c509: document ethtool support
2.6.32-stable review patch.  If anyone has any objections, please let us know.


From: Ben Hutchings <>

commit aa4e2e171385bb77b4da8b760d26dea2aa291587 upstream.

3c509 was changed to support ethtool in 2002, making the 'xcvr' module
parameter obsolete in most cases. More recently 3c509 was converted
to the modern driver model and this parameter was removed. Fix the
documentation to refer to ethtool rather than the module parameter.
