It's a very simple change (disable the other 7043 clock output - not required in theory but let's be paranoid - and change dac_refclk back to 0). The sysref phase doesn't have an impact on PRBS. https://github.com/m-labs/artiq/issues/1080#is

<GitHub-m-labs> [artiq] sbourdeauducq commented on issue #1080: No, that's unlikely to help. The other clock is either unrouted or routed to the other quad for DRTIO.

<GitHub166> [smoltcp] podhrmic commented on pull request #236 200ec19: I am not familiar with Ipv6 so I cannot comment on how similar to IPv4 it is. But it can be refactored in the future, if someone with more knowledge about Ipv6 can pitch in. I would keep it separate for now, better some fragmentation support than none:-) https://github.com/m-labs/smoltcp/pull/236#discussion_r197857557
<GitHub194> [smoltcp] podhrmic commented on pull request #236 200ec19: There is a thread in the old PR where I tried to explain why `ManagedMap` doesn't work. In short, to insert a new packet to `ManagedMap` you need to allocate memory for it somewhere. And either you create a new `Vec<u8>` which is easy but requires `alloc`. Or you have a static buffers somewhere, and that effectively makes it a `ManagedSlice`.... http

<GitHub8> [smoltcp] podhrmic commented on pull request #236 dcbc010: Edit: I realized even the `loopback.rs` example you have to run with at least `alloc` because of the `From` trait implementation. This definitely limits smoltcp's usage on bare metal systems:-( https://github.com/m-labs/smoltcp/pull/236#discussion_r197863000

<GitHub-m-labs> [artiq] philipkent commented on issue #888: @dhslichter We will be moving to ARTIQ 3 soon and we're planning on having to setup a development environment to compile gatewares with the expanded FIFO depths. Would it make sense to update the FIFO depth's in the pre-compiled gatewares in the nist_qc2 conda package for ARTIQ 3 to be at least 1024 sense that seems to be what everyone is using? https://github.
<GitHub-m-labs> [artiq] dhslichter commented on issue #888: Yes, I think that sounds sensible. There are separate input and output FIFOs, and I would suggest that we would make better use of the resources available if we make the input FIFOs relatively small (say 128 or 256) except on a few special channels, when we make them much deeper (16k or so). Then we can hopefully fit 1024 on each output, which would be nice. @r-sri
