Thanks for the report!
The error looks somewhat odd; the code says "SIOC_IN" and the error suggests to
use SIOC_IN?
Unfortunately, upstream is dead and I have no experience porting or
cross-compiling C code. Any suggestions for how one could fix this?
I found https://patchwork.ozlabs.org/patch/740563/ via some googling. It
mentions MIPS, so it might be related?
Kind regards,
Ralf
