How to add background for texttt (and allow line breaks)

Question

I use texttt{} to write names of software, commands etc. within the text. Sometimes the texttt text is longer and there is a line break within it. It works well, no problem here.

I wish to add background to that text. I modified the texttt command:

\renewcommand{\texttt}[1]{\colorbox{Ivory}{{\ttfamily #1}}}

The only problem with this solution is that it doesn't allow line breaks.

Minimal working example

\documentclass[a4paper, 11pt, twoside]{article}
\usepackage{xltxtra}
\usepackage{xunicode}
\usepackage{polyglossia}
\usepackage[svgnames]{xcolor}
% Modify page margins
\usepackage[a4paper, text={160mm, 250mm}]{geometry}
% Add background for \texttt{}
\renewcommand{\texttt}[1]{\colorbox{Ivory}{{\ttfamily #1}}}
\setdefaultlanguage{english}
\begin{document}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec quis

arcu a est sollicitudin euismod. Nam libero tempore, cum soluta nobis 
est eligendi optio cumque nihil impedit quo minus id quod maxime placeat 
facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. 
Maecenas lorem. Sed ut perspiciatis unde omnis iste natus error sit

\end{document}

doesn't work as expected...

You can use the package soul and its highlighting feature.

\usepackage{soul}
\sethlcolor{Ivory}
\renewcommand{\texttt}[1]{\hl{\ttfamily #1}}
