Kernel 5.15 removes net/ipx.h, which breaks compilation:

/build/source/core/rtw_br_ext.c:20:11: fatal error: net/ipx.h: No such file or directory
   20 |  #include <net/ipx.h> // https://github.com/tomaspinho/rtl8821ce/blob/897e7c4c15dd5a0a569745dc223d969a26ff5bfc/core/rtw_br_ext.c#L20
      |           ^~~~~~~~~~~

Replacing it with <netipx/ipx.h> from glibc results in the following error:

I (dirty) fixed this here: https://github.com/egnappahz/rtl8821ce.git

I already submitted a merge request to notice the maintainer

I can also confirm this works for me, without any issues AFAIK. I'm on 5.15.2-arch1-1.
