Your question is missing a key piece of information. The big bit that you left out is what protocol you want to try to process with Wireshark.
Is it MPEG2 transport stream, or WiFi, or ZigBee, or something else ?
Wireshark is a binary protocol analyser. So before Wireshark can do anything you need a raw demodulated binary bitstream in a format that Wireshark can process.
A LimeSDR captures RF signals and converts them into an IQ steam, which is still a modulated signal, or multiple modulated signals.
So the piece you are missing is the demodulation of a raw IQ datastream into a format that Wireshark can analyse. And that demodulation will be totally different, depending on the protocol. My starting point would be to look through possible gnuradio recipes ( https://github.com/gnuradio/gr-recipes ) and etcetera ( https://github.com/gnuradio/gr-etcetera ) to see if someone has done something that I could use to output maybe a UDP stream. But if the demodulation is niche or new, you may have to create your own.
