[PATCH] rxe_cfg: Fix parsing of ethtool / ifconfig

[Nathan Hartwell <nathan.hartwell@xxxxxxxxxxxxxxxxxx>]

rxe_cfg does not always parse the output of ethtool and ifconfig correctly.

Fix two items:
1)  Parsing of ethtool's link speed field to always output a link speed.
2)  Parsing of ifconfig's IP address / MTU fields with newer builds of
ifconfig that have a slightly different output format than in the
past.
