From 2960e559515348dce83bfdbdd6ef39e551235045 Mon Sep 17 00:00:00 2001 From: Sugandha Gupta Date: Fri, 25 Jan 2019 17:36:26 -0800 Subject: device3: Constraint send/recv_frame_size based on down/upstream MTU We need to properly contraint the send/recv_frame_size based on the minimum MTU of all the down/upstream blocks. This fixes the issue with E310 tx/rx streaming as it has smaller MTU sizes than the other usrps. --- host/lib/usrp/e300/e300_impl.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'host/lib/usrp/e300/e300_impl.cpp') diff --git a/host/lib/usrp/e300/e300_impl.cpp b/host/lib/usrp/e300/e300_impl.cpp index 59a8cec88..5a6376039 100644 --- a/host/lib/usrp/e300/e300_impl.cpp +++ b/host/lib/usrp/e300/e300_impl.cpp @@ -731,6 +731,11 @@ uhd::both_xports_t e300_impl::make_transport( return xports; } +size_t e300_impl::get_mtu(const size_t /*mb_index*/, const uhd::direction_t dir) { + return (dir == RX_DIRECTION) ? _data_xport_params.recv_frame_size : + _data_xport_params.send_frame_size; +} + void e300_impl::_update_clock_source(const std::string &source) { if (source != "internal") { -- cgit v1.2.3
