with a pre-existing reference design based on the QCA9531. that has a<br>
PCIe interface, USB2 and a 5-port GbE *and* a 2x2 2.4ghz WIFI antenna.<br>
full source is available for everything so it can be entirely libre<br>
and RYF Certified.<br>
<br>
the advantage of having an EOMA68 Card in the router should be clear:<br>
the Card will have considerably more resources: RAM, CPU cycles etc.<br>
meaning that VPNs can be done without high latency, yet take advantage<br>
of the LAN capabilities of the 5-port... you could put in a MiniPCIe<br>
Card (a *proper* one) e.g. a 3G/4G/LTE Modem, WIMAX, 802.11ac... blah<br>
blah.<br>
<br>
the tricky bit: connecting the EOMA68 Card to the QCA9531. now, i<br>
took a look at the Reference Design and i *really* do not want to<br>
touch the layout for the GbE, WIFI or PCIe. so i figured, why not<br>
connect the EOMA68 USB2 host interface back-to-back with the QCA9531's<br>
USB host?<br>
<br>
turns out that something called the Cypress AN2720 can do exactly<br>
that, and it comes up as a cdc_subset of the usbnet linux kernel<br>
driver. yay! quick search online: the datasheet is publicly<br>
available, easy to find on digikey. yay!<br>
<br>
so i would assume, because it's not an actual 10/100 ethernet, that it<br>
would run at (saturate) the full 480mb/sec of USB2. so not quite GbE<br>
speeds but pretty damn close. yay!<br>
<br>
anyway should be quite straightforward.<br>
