糞エアリアの LAN EVOLUTION の firmware として最初から入ってる Linux を立ち上げて、(初めて)WEB画面にアクセスして確認してみたら、mac adderss は 00:22:ec:02:00:f3 になってた。
今使ってる 00:aa:bb:cc:dd:10 は、LAN EVOLUTION の U-Boot の flash の環境変数領域に設定されていた値で、U-Boot の tftpboot はこのふざけた mac address で boot しやがるのですが、 やっぱりどっかにちゃんとした mac address が書かれているんだなぁ。どこだろう。まぁ 00:aa:bb:cc:dd:10 のままでもいいんですが。
というわけで、イーサの続きを書く。
受信時のCRCを含めるか含めないかのビット操作に気づかなくて少しハマったものの、一応 nfsboot でシングルユーザまで動いた。
たまに boot 中に RX FIFO FULL でドライバが止まったりするけど。
パフォーマンス出てないっぽい。CPU のデータキャッシュが disable なままだったり、ドライバがまだヘボヘボチューニングなのもあるけど、根本的に遅いのは RX ring buffer の充填を auto polling にしてるのが悪いんじゃなかろうか。
自前でDMAをハンドリングするように変えてみよう…
