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!

On pi3 I'm running spi at 25Mhz (with dma). There's a secondary sdio interface which can do 25Mhz (maybe 50) using 4 gpio pins as a wider bus, but we have no driver for that.

Incidentally, the original raspberry pi linux kernel only supported programmed i/o for spi. If the documentation for the bcm2835 SoC had been the usual "just read the linux driver" that most vendors consider adequate, we wouldn't have known how to speed up the spi with dma. I wonder how well this ESPRESSOBin board and SoC will be documented? The kickstarter blurb lists a "host of operating systems" they say they will support, but they're all linux.
