Hi Eugene,

Hi Eugene,
I'm not an expert on the PCIe transport, but as far as I can tell from
3.11.0.1's
uhd::transport::muxed_zero_copy_if::sptr make_muxed_pcie_msg_xport
the PCIe frame sizes seem to be immutable (4 kB, in fact, which,
subtracting header and dividing by sample bitwidth, leads to 1020
Is there a way to specify the frame size on the PCIe interface? I tried using
the same keywords as for the NIC, but it had no effect. I need low-latency and
the default frame size is 5000 bytes (much too large for my needs).
