[Buildroot] [git commit] hostapd: add support for Realtek driver

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=5a0cfbded075dea4a0416ffcfe7407b8db91d0a4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since kernel drivers for Realtek wireless chips use non-standard
interfaces, upstream hostapd does not support them. One have to apply
an external patch for hostapd to work with these chips. See:
https://github.com/pritambaral/hostapd-rtl871xdrv

A configuration option is added to enable support for Realtek chips,
and it's turned off by default.
