I think this license is an ISC license.

However, MODULE _ LICENSE declares a different license.
I don't know which license is correct.
What licenses are declared in this file?

I am a little confused. If the author(s) declare the license to be "Dual  
BSD/GPL", why do you not believe them?

I judged it as an ISC license because the text in the file matched the text in the ISC license.
I am referring to SPDX license list.
https://spdx.org/licenses/ISC.html

I think that the license for this file is "Dual MIT/GPL" if I believe this license text.
