Random "war stories" that could be clues for OP ensue... I'm not vouching how suitable this all is, but your comment "one NIC plus a G= igE switch" made me think Hiro. I'm pretty certain we don't have "nice toys"= like MPLS and all that cool cat stuff that become big in the days of the Co= mmindico IP transit network here in Oz, the first real nationwide backbone I= P network to compete with Telstra (the Big T had been deregulated and sold b= y the Howard Government a few years beforehand, but no one had gotten around= to knocking the Big T off their perch - until Commindico, circa 2002 - 2003= iirc). Anyway, me as PFY linesman in 2004, had to do some minimal Cisco stuff, MPLS= was mentioned, usual sales pitch, whatever. Cisco sucks the big one, by the= way, but that's just me. I'm into UBNT gear these days, but I get a great s= ales pitch, and neat wholesale tacked on the back of a WISPs orders. Family i= s great, especially adopted family. My idea, subject to it physically working in the Plan 9 stack and whatnot fo= r OP using your suggestion Hiro is to hook up said Plan 9 box to router of t= ype to be a little smarter than the average router, which gets around some o= f your "routing issues" I'd imagine the OP might want to play with. https://routerboard.com/CCR1009-8G-1S-1Splus You start partitioning your bandwidth in this case, and from a Pi you've got= barely 100Mbit off the Ethernet interface, and the single USB PHY feeding a= ll your USB devices and the Ethernet, even on the ARM64 Pi3, although I am h= oping Eben got with the program and got rid of his little bug in the silicon= in the USB PHY, I had a few issues with it working tech for the Uni's in Sy= dney building CubeSat components back when. Model A+ spec gear. Lucky for me= , I strapped the FPGA card on through the SPI interface, and had a bit of SD= RAM buffering what was coming off my acquisition gear. You avoid Pi USB issu= es when you have an ARM board with a dedicated MAC+PHY, usually swings off s= ome adaption of the MII gear that hung off the back of Sun SPARCs into Thick= net transceivers back when, just without the thick chunk of multicore copper= between system and transceiver. Evidently OP knows a trick or two, and yes,= you're right. I mention all these anecdotes for your entertainment. If Plan 9 runs on this= Kickstarter board, sweet as, I'll buy one eventually. I was going to try to= get one of the boards from the German guy, the one with the funny Japanese n= ame, and the Zynq CPU... Then I lost my job, went completely broke, moved up= North, and am now trying to work on farming dairy goats. That's a long story for another time kids. Almost final thought - I've wanted to play with this MikroTik gig I linked a= fter I first saw it at the adopted family members place I refer to above, in= his little data centre for the WISP. Took down a model number, Googled it, a= bit like the Parallella gear I was playing with six months to a year before= I lost my job, and had to move up North. I had always thought the Epiphany c= hip would be good for a Plan 9 or better yet, an Inferno port, again, story f= or another time. The CPU on the Parallella is the same Zynq ARM+FPGA on the f= unny Japanese name board. The Tilera CPU in the MikroTik I refer to is simil= ar, all RISC spec crap, grid stuff, all GCC toolchains. Strap a MII IP core i= n a Zynq FPGA, wire to MAC+PHY chip? Second LAN then? Could do a SATA interf= ace similar, don't know what you'd spring for an IP core. More than a mortal= such as I? I've been out of this for almost two years, I know nearly squat t= hese days. PS - I once asked Mr Stallion about a port to of Plan 9 to the Dragino. Tech= nically quite possible, financially not my gig. That could've got you out of= trouble OP, use ARM board for CPU horsepower, squirt through wifi/ dual rou= ted LAN on Dragino. No hard feelings Steve, I wish I'd had the money, there'= s new Dragino gear out, ones an outdoor VoIP endpoint, like the Aussie Rowet= el stuff was supposed to be. Apologies for hijacking thread with barely, struggling to be relevant, thoug= hts. War stories from too many years doing... Think I was drunk for a lot of= it? Oh well. Enjoy!
