Documentation: e100: Update the Intel 10/100 driver doc
Browse files Browse the repository at this point in the history
Over the years, several of the links have changed or are no longer valid
so update them.  In addition, the default values were incorrect for a
couple of parameters.

Converted the text file to the reStructuredText (RST) format, since the
Linux kernel documentation now uses this format for documentation.
