<div dir="ltr">An AP's radio complex may have a CPU but that doesn't mean it is the standard linux stack as most think of it. Many consider this as part of "firmware" which can be Linux, a Linux derivative or other. Also, there are some levels of wired/wireless forwarding plane integration done at the hardware level that many might be surprised by. <br><br>Bob</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 22, 2022 at 12:03 PM David Lang <<a href="mailto:david@lang.hm">david@lang.hm</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">On Tue, 22 Nov 2022, Bob McMahon via Make-wifi-fast wrote:<br>

APs forward packets within the switch at the hardware level, but the radios have <br>
to go through the CPU, so any wired <-> wireless needs to go through the CPU, <br>
and I would be incredibly surprised if the wifi chips did wireless <-> wireless <br>
routing at the hardware level.<br>
