OK, I ordered 2. It's not clear how the ethernet is fully implemented (The marvel phy is documented, the actual ethernet interface is not so far as I can see, so some source code reading is going to be required. ) I note that me doing this is also kind of driven by supplies of the wndr3800

2012-12-20 Thread Alessandro Bolletta
Hi everybody, Today i made some tests on my tplink home router powered by the lastest snapshot build of Openwrt. So, i configured tc to make fq_codel the default queuing algorithm for 2 eth ports available on the router (leaving unchanged default values). So, i started some TCP sessions through
