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/mpmd/mpmd_impl.hpp | 3 +++ 1 file changed, 3 insertions(+) (limited to 'host/lib/usrp/mpmd/mpmd_impl.hpp') diff --git a/host/lib/usrp/mpmd/mpmd_impl.hpp b/host/lib/usrp/mpmd/mpmd_impl.hpp index f74627afa..bdb6bd691 100644 --- a/host/lib/usrp/mpmd/mpmd_impl.hpp +++ b/host/lib/usrp/mpmd/mpmd_impl.hpp @@ -246,6 +246,9 @@ public: uhd::usrp::device3_impl::xport_type_t, const uhd::device_addr_t&); + //! get mtu + size_t get_mtu(const size_t, const uhd::direction_t); + private: uhd::device_addr_t get_rx_hints(size_t mb_index); uhd::device_addr_t get_tx_hints(size_t mb_index); -- cgit v1.2.3
