Hi,

have a look at:

https://github.com/AVnu/OpenAvnu

There you can find the entire AVB driver stack and subsystem. Along with 
some Gstreamer and Jack Audio examples.

 Just received two of these (HP) I-210 "PCI 2.1" cards (from Amazon). 
 Installed one of them in and old PC with a PCI-e 2.0 x 4 slot (thus only 
 using part of the slot). Initially windows reported an error and it did 
 not work. Went back to Ubuntu 17.10 on the same machine and it worked 
 fine. (Same result as another person before me). Disabled the internal 
 NIC and started Windows again. Voila, it worked ! Re-enabled the 
 on-board NIC and it kept Working in windows. Just for reference.  Don't 
 have a AVB audio device so cannot really test them. Looking if there is 
 any AVB test software out there to use these two cards to transmit AVB 
 based audio from one to the other.

  From talking to Focusrite regarding AES67 and the Rednet series and 
 firmware support, got the following:  "With regards to AES67 
 compatibility, this is possible for devices using the 'Brooklyn 2' Dante 
 chipset. RedNet 3s ship with a 'Brooklyn 1' chipset, though it's 
 possible to upgrade to a Brooklyn 2 (this would be chargeable). All of 
 our devices using Brooklyn 2 modules have AES67 compliance following the 
 latest firmware update available from RedNet Control"  (Focusrite 
 Rednets use the Bonjour/mDNS protocol for discovery)

 In conclusion, the 3 parts needed for full functionality on Linux
 [1] Discovery - mDNS should be doable in Linux, right ?
 [2] AoIP  / clocking - This AES67 project
 [3] Control (of the device) - Windows/Mac for the moment. Hopefully 
 suppliers will support some kind of new standard in the future for that 
 as well ( HTML XML, JSON  or other open messaging over IP to configure 
 the unit). The Rednet3 will keep the routing/configuration after power 
 cycling thus until then that should be done under Windows.

 Looking forward on the progress  of this project !

 A few years back there had been a AES67/Ravenna implementation. But 
 the developer and ALX Networks could not agree on the license. The 
 developer wanted to publish it under GPL, which ALX Networks did not 
 want. So the implementation was dumped. Well, that is the story how I 
 know it.
 The developer was Florian Faber, but he is no member of the jack-devel 
 or linux-devel list anymore. Perhapes, he might have some useful 
 insights, if you manage to find a contact. ;-)

 There are some different I210 card versions it seems, any 
 recommendations ? 

 They are all ok. I have different versions myself: Intel I210, HP 
 I210TI. But make shure it is no I217, because they have no traffic 
 shaping queues. Although they suport HW PTP timestamping.

     With an Intel I210 NIC you can already have AVB in combination with
     Jack. But you have to do some coding yourself to fit your purposes..

     BTW:
     I would never recommend buying MOTU.

         MOTU just released the 828es with AVB and USB standard compliant
         and two ADAT I/O and Web based (not ALSA) mixer. That would be,
         for now, the ultimate (AVB)  interface for Linux,  if it works.

              That is such good news.  What(low cost)  hardware would

              * MOTU LP32 (Preferred)
              * MiniDSP

              I hope someday it will be possible to connect 4 or more 8
         channel
              ADAT modules (32 channels) to a PC under Ubuntu via AVB
         with low
              latency. The only option to get this done under Windows 
 is a
              Focursrite DANTE based Rednet 3 right now because
         Thunderbolt is not
              really available there as well. Plan to get Rednet3,  but
         that does
              not solve the Linux environment which I prefer. Would love
         to be
              able to use the Rednet 3 under Linux but since DANTE is
         proprietary
              , so unlikely.

              My two wishes:
                 [a] Multi (16+) channel low latency audio I/O using ADAT
         audio AD/DA
                 [b[ Bitwig  supporting LV2 plugins.

              With those two,  the Linux Audio environment would be
         perfect and
              the world a better place.
