Hi, I'm one of maintainers for ALSA firewire stack, which handles IEC 61883-1/6 and vendor-unique packets on IEEE 1394 bus for consumer recording equipments. (I'm not in MAINTAINERS because I'm a shy boy.) IEC 61883-6 describes that one packet can multiplex several types of data in its data

[very-RFC 0/8] TSN driver for the kernel

Hi all (series based on v4.7-rc2, now with the correct netdev) This is a *very* early RFC for a TSN-driver in the kernel. It has been floating around in my repo for a while and I would appreciate some feedback on the overall design to avoid doing some major blunders. TSN: Time Sensitive
