Subject[PATCH v2] staging: rtl8188eu: Fix private WEXT IOCTL calls
Date
From: Ishraq Ibne Ashraf <ishraq.i.ashraf@gmail.com>

Commit 8bfb36766064 ("wireless: wext: remove ndo_do_ioctl fallback") breaks private WEXT
IOCTL calls of this driver as these are not invoked through ndo_do_ioctl
interface anymore. As a result hostapd stops working with this driver. In
this patch this problem is solved by implementing equivalent private IOCTL
functions of the existing ones which are accessed via iw_handler_def
interface.
