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 samples per frame).
