Not that I think these guys are legit, but GigE switch silicon seems to be hard to come by in low quantities. It's a problem I've been having for my work. None of the chips I've found appear to be available, unless you are talking quantities in the 50K range. [I have a few more parts to chase down, but reps have been slow to respond] If anyone has a line on one that is readily available [in sub 100pc quantities], I'd love to hear from you. [Specifically I've been looking for 5 port unmanaged solutions (or 4+1)]

Really?Marvell part, no data, no real supplier? Not for production, I don't, not with a bargepole...
Marvell's approach to data makes it (almost?) impossible to use them in an open source project.
The bastards bought the Stongarm PXA2xx from Intel, and locked it right down, after we were shipping. (I have a long memory...)
Every encounter I've had with them (in the annoying thousands, but not hundreds of thousands volumes) has been a tedious crapfest of NDAs and still inadequate documentation, which had to be wrested from them, page by page. They're right at the bottom of the pile, when it comes to choosing chips, for me. Maybe I was just doing it wrong? Hints would be welcome, they've often got silicon that looks tempting, but I just can't be arsed any more.
The Soap boys are well out of it if they can avoid Marvell, in my opinion.

Ebay is not a reliable source for production [it needs to be available through a listed rep or distributor for me to even consider it]. My local Marvell rep is one of the slow responders, so they are still an option, if anyone ever gets back to me. [But I to have had bad experiences with Marvell, so they are not high on my list. On a previous design they refused to even engage because I wasn't talking about 100K units, I'm hoping that's not the case again here]

That's odd...must depend on the chipset you are looking at? My company regularly does small runs (much, much less than 100K qty) of very niche designs and we use Marvell GigE PHYs & switches in a majority of them.
I've also been able to request samples of Marvell parts without much fuss. Maybe you just need to wine and dine your Marvell rep?

I'm beginning to suspect they work differently in the USA...
In the UK, they're repped through a company that doesn't have a website, or you can take your chances with Avnet, which isn't so bad, but is where unloved products go.

The 100K was for the Armada Processor and companion chip. [it's the processor used in the reference Google TV design] And in that design My quantity was around 10K/yr!
I have used Marvell chips in other designs, poor documentation, but the chips work as desired. As I said I'm still waiting for a response from the rep on this one... it is summer vacation time around here, so that may explain the delay.

Haha, you can say that again! Last Marvell chip I worked with, 88E7221, many of the SoC registers were marked "TBD" in the datasheet.
Does this update make any sense?
"As you may know that the IMX6 has bandwidth limitations with their gigabyte ethernet that peaks around 470 mbps. We have had to use a gigabyte ethernet solution like intel to circumvent this speed limitation but our solution as of now is to use a part from freescale or intel that will put a router/switch on the single port solution from intel. We have been talking with intel, marvell and freescale on our final solution but it will be something similar to the one i have laid out"
They still use "gigabyte" when talking about gigabit ethernet, I cannot take them seriously at all.
Routers capable of 1GB/sec are available
such a router costs a fortune ! 1GB/s = 8Gb/s . even a L3 switch capable of routing such a traffic is still freaking expensive.

My guess from deciphering the gibberish: Intel GigE PCIe chip (so they can actually get 1Gbit/s, "single port solution"), connect that to a switch from Intel/Freescale/Marvell to get the rest of the ports.

Well: "As you may know that the IMX6 has bandwidth limitations with their gigabyte ethernet that peaks around 470 mbps"
Since the gigabyte interface only does about 470 millibits per second, I'd say that's a severe limitation.

Typo.
typo is something you do once, maybe twice if you are terribad at keyboard, now when you use same word over and over without understanding its meaning

No, it is not. http://routerboard.com/CCR1009-8G-1S
That's a 1 gigabit router not an 8 gigabit router, which is what is being implied by the GB/sec (gigabyte) instead of Gb/sec (gigabit). [technically it would have to be a 10Gb router, as that is the next step from 1Gb]

They can still deliver 10Gbit router if they really want to, AMD started shipping 2x10Gbit ARMv8 dev kits ($3K) this week

btw... if a router has 10Gbit interfaces, it doesn't necessarily mean it's capable of routing @ 10Gbit/s
Especially with on-the-fly virus scanning on every routed packet.
Indeed, they are taking about going beyond carrier grade DPI.

I was talking about using GB instead of Gb. What are you on about?
And yes, I have arthritis in my hands, I do typo stuff all the time.
I'm pretty sure he was talking about this:
"As you may know that the IMX6 has bandwidth limitations with their giga
byte ethernet that peaks around 470
mbps. We have had to use a giga
byte ethernet solution..."
As he said, a typo is something you do once, on accident. Calling it gigabyte vs gigabit TWICE in as many sentences demonstrates a clear lack of understanding, either that or a shady attempt to prey on the lack of understanding in their audience. Based on their "millibits per second" usage, I'm going with a lack of understanding.
Another interesting fact - one of the chips on the
bottom side of the board is presumably SMSC LAN9500. Why the hell would anyone want a USB to ethernet chip on a router?
And regarding OSC6, as someone was speaking about earlier, the soldering job has been
done as expected to avoid the collision between ethernet connector's pads and case of the oscillator, just notice those "floating" crystals
i assume the SMSC LAN9500 USB ethernet is the WAN port and the end of life Micrel KSZ8895 is forming a managed LAN switch.
but the guys apparently didn't realize the USB Ethernet will eat up a lot of cpu cycles - considering all the features they're promising... well... i think many of the $80 SOHO routers will outperform the SOAP in terms of throughput.
