<span id="id1"></span><h1>igb<a class="headerlink" href="#igb" title="Link to this heading"></a></h1>
|
||
<p>igb is a family of Intel’s gigabit ethernet controllers. In QEMU, 82576
|
||
emulation is implemented in particular. Its datasheet is available at <a class="footnote-reference brackets" href="#id7" id="id2" role="doc-noteref"><span class="fn-bracket">[</span>1<span class="fn-bracket">]</span></a>.</p>
|
||
<p>This implementation is expected to be useful to test SR-IOV networking without
|
||
requiring physical hardware.</p>
|
||
<section id="limitations">
|
||
<h2>Limitations<a class="headerlink" href="#limitations" title="Link to this heading"></a></h2>
|
||
<p>This igb implementation was tested with Linux Test Project <a class="footnote-reference brackets" href="#id8" id="id3" role="doc-noteref"><span class="fn-bracket">[</span>2<span class="fn-bracket">]</span></a> and Windows HLK
|
||
<a class="footnote-reference brackets" href="#id9" id="id4" role="doc-noteref"><span class="fn-bracket">[</span>3<span class="fn-bracket">]</span></a> during the initial development. Later it was also tested with DPDK Test
|
||
Suite <a class="footnote-reference brackets" href="#id10" id="id5" role="doc-noteref"><span class="fn-bracket">[</span>4<span class="fn-bracket">]</span></a>. The command used when testing with LTP is:</p>
|
||
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>network.sh<span class="w"> </span>-6mta
|
||
</pre></div>
|
||
</div>
|
||
<p>Be aware that this implementation lacks many functionalities available with the
|
||
actual hardware, and you may experience various failures if you try to use it
|
||
with a different operating system other than DPDK, Linux, and Windows or if you
|
||
try functionalities not covered by the tests.</p>

<section id="using-igb">
|
||
<h2>Using igb<a class="headerlink" href="#using-igb" title="Link to this heading"></a></h2>
|
||
<p>Using igb should be nothing different from using another network device. See
|
||
<a class="reference internal" href="net.html#network-emulation"><span class="std std-ref">Network emulation</span></a> in general.</p>
|
||
<p>However, you may also need to perform additional steps to activate SR-IOV
|
||
feature on your guest. For Linux, refer to <a class="footnote-reference brackets" href="#id11" id="id6" role="doc-noteref"><span class="fn-bracket">[</span>5<span class="fn-bracket">]</span></a>.</p>

<h2>Developing igb<a class="headerlink" href="#developing-igb" title="Link to this heading"></a></h2>
|
||
<p>igb is the successor of e1000e, and e1000e is the successor of e1000 in turn.
|
||
As these devices are very similar, if you make a change for igb and the same
|
||
change can be applied to e1000e and e1000, please do so.</p>
|
||
<p>Please do not forget to run tests before submitting a change. As tests included
|
||
in QEMU is very minimal, run some application which is likely to be affected by
|
||
the change to confirm it works in an integrated system.</p>
