ethtool.sh didn't reset the Internal Field Seperator (IFS) properly.
It now does, by storing the old IFS to OIFS, which will be used later
in the for loop.
It also fixes the "ethtool_ring_<if>" option.

Implement a consistent interface for changing ethtool parameters, as
suggested in bug 195479. All variable names are based on the long option
to ethtool to set each group of parameters. Multiple entries seperated
by newlines are permitted for variable values.
