I wonder if treating WiFi like a transceiver is the better approach,
separating "the computer abstraction" from the remote radio head.

Then it's a RF Front End(s) / CMOS Radios / PHY(s) / 802.11 MAC(s) (lower)
/ 802.3 PAM4 / 100G SERDES / 4 1x25G VCSELs. Pluggable like an SFP.

The virtualized APs could support at least 10 and maybe 100s of these via
merchant switching silicon and could be kilometers away. The MACs lower
could be simplified to dual queue a la L4S. No need for 4 AC queues per
MAC. Might be able to throw away 802.11 retries too and let the upper
layers handle it.

May be a good time to simplify.

Bob
