Ok, so it's really no wonder about these,
those proprietary are hendeled transparently by an ASIC or an FPGA.

so this won't be the case with AVB,
i suppose at low sampling (48k or 44k1) it will work over a regular
network, provided the host is doing only AVB streaming and there is
no other trafic on the network.
I'm not intery sure how stream reservation would work, but may be
you can fake it in software somehow.

there is PTP driver patch here:

it seems to be ptpv1 ..hm
this ptpd list thread is about patents:

could these patents be such a problem?
will AVB support have to be distributed trough patches because of this?

well ..i haven't used Netjack or anything, so cannot tell.
