MARIAN has an ALSA driver for their Clara E PCIe interface. It's a DANTE card, so it's going to be of limited use to those of us with home studios.

That said, they do have the Clara B and B+.
*24 Bit / 192 kHz Resolution (digital connections)
*32 Bit / 384 kHz Resolution (Analog Connectors)
*1 AES/EBU In- and Output (4 channels)
*2 Analog In- and Outputs (4 Channels)
*2 MIDI In- and Outputs ("+" version)
*Auto Mute of Outputs on Start-up of Computer
*Low Profile for Server-, Mini- oder Media Computer * long slot bracket for normal cases included
*Balanced XLR Connectors
*Switchable Input SRC with 144 dB Dynamic Range
*Beast DSP Mixer with EQ
*Cascadeable (via TDM SyncBus)

That's a list of all kinds of neat, and I would like to have an alternative to my RME AIO Pro.
So I emailed them about the possibility of extending Linux support to their other cards.
That's a definitive maybe, one day... when we get around to it.
