+ (dot11 | MAC & PHY) * (1.0 / 4.0);

"IEEE802.11 MAC and PHY"な"すたんだーどどらふと"(?)を更に1/4程消化．
直接ナントヤラと赤外線なPHYなので，残り半分はすっ飛ばした．
明日，上司の方にHardMACとSoftMACの境目を教えてもらったら，
ブツの仕様書を書く事になっているけど，どーなるんでしょーかー？ :P
["IEEE802.11 MAC and PHY" as known as the standard
draft, plus about 1/4 is DONE.
DS thingy and InfraRed thingy of PHY are skipped as a 1/2 of
that draft.
Tomorrow, once my bosses tell me about boundary of HardMAC
and SoftMAC thingy, I'll do write down its spec or so.
Well, who knows what will happen? :P]

で，感想．
重要なのは分かるけど，backward-compatって新しくモノを作る時は，
大方足枷になるっぽい．
アレなbackward-compatな仕様だったので読むのが大変だった．
と言う訳で，Abandon! Abandon! :P
[My impression is,
I know a backward-compat is a really important thing, though.
But those many considerations drive me nuts, I'd have to say.
All I would say is "Abandon! Abandon!" :P]
