<p class="MsoNormal"><span style="font-size:10.0pt;color:#1F497D">Something seems to be wrong with the mail server – lots of email just now showing up. Yes, that last line down there was not used and is removed in the pending patch. Yes, you’re in the right
place to add mapping of addt’l BARs if your hw has them. Let me know if you have problems getting it working – as NVMe doesn’t use the other BARs we wouldn’t be looking for that code to be contributed back of course…<o:p></o:p></span></p>
