Yes the source is in a ZIP file that I made available here: https://github.com/samerhaj/uefi_drivers/blob/master/UsbNetworking/Asix/zip/source/AX88179_178a_UEFI_v2.9.0_Source.zip Will add a reference in v2 > Also, semantics - could you say "provided" rather than "contributed"?

I have no clue. The code came from ASIX with these Intel copyrights. I just updated the license from "BSD License' to "BSD-2-Clause-Patent". I also noticed the original drivers carry the Intel copyrights, and have been so since the initial contribution: e.g. https://github.com/tianocore/edk2/commit/8dde1f6e9574967b71dc4c6ca15cb7cfd16b38a5 I am speculating, but maybe Intel wrote the original code, and ASIX never added their copyrights? > > + > > + > > +#define PASS_SCT 0 > > O'Rly? > This shouldn't even be possible to disable. 😊 Hey I am just the messenger.
