Wireshark F5 Plugin - Unable to locate file

The last couple of hours I've spent attempting to install the F5 plugin for Wireshark. The directions I've followed are on this DevCentral article. Here's where I am at:

1) Downloaded the Wireshark source tarball.

2) Extracted the file.

Step 3 says to extract the files in the F5 package, but there is no F5 package there. I have a wireshark-plugin.f5ethtrailer.bin.1.11.zip file I downloaded from DevCentral, but that's not what is being asked for I don't believe.

There's a comment in the Notes section that says the following:

When compiling on Windows, you need to pretty much build the entire WS distro due to the way Windows handles DLLs. For Linux (and I believe Mac, but I’m not sure), you can get the sources all setup, add in the plugin source, run configure and then run make only in the plugins/f5ethtrailer directory

This makes me believe I need to uninstall and reinstall Wireshark entirely. Is that so? Not sure what I'm doing wrong here. Any help would be appreciated!
