I suspect that the new TFO code hasn't been tested much on mips. Am<br>
glad you are doing so!<br>
<br>
I got my replacement wndr3800s a few days ago, and will put the next<br>
build through the TFO wringer (as well as attach a serial console).<br>
That said, perhaps your bug report best belongs on netdev where there<br>
are a couple people working hard on TFO and at least one has a cerowrt<br>
capable box...<br>
<br>
Does TFO successfully pass through the router?<br>
