https://github.com/void-linux/void-packages/issues/35569

Description:
### System

* xuname:  
  `Void 5.15.17_1 x86_64 AuthenticAMD notuptodate rrrrmmnFFFFFF`
* package:  
  `rtl8812au-dkms` ver: `20210427_1`

### Expected behavior
Driver compiles successfully.

### Actual behavior
`make` fails with error (logfile: `/var/lib/dkms/rtl8812au/5.9.3.2/build/make.log`):
`net/ipx.h: No such file or directory`

### Steps to reproduce the behavior
- Use Linux kernel 5.15 or above
- Install package `rtl8812au-dkms` from repo using `xbps-install -Su rtl8812au-dkms`
- DKMS fails with a fatal error that says to check the logfile which then says that there's a missing file or directory:
> **DKMS module 'rtl8812au-5.9.3.2' failed to build, please check /var/lib/dkms for errors in the log file.**

### Fix
After replacing the code in `/var/lib/dkms/rtl8812au/5.9.3.2/core/rtw_br_ext.c` with the code in the comment linked below, the driver compiles successfully.
