Any particular reason for enabling this? The driver does not
specifically need it. The option only allows use of WEXT dependent
user-space tools like iwconfig and iwlist. At least it is not needed by
brcmfmac driver hence it does not select it.
You indicate there is a dependency. Could you elaborate?
"Dependency" probably isn't correct.
However, the intent of tegra_defconfig is to provide a useful
configuration for Tegra boards. Without the ability to use
iwconfig/iwlist, enabling the wireless driver doesn't seem useful; how
would someone configure the wireless connection?
Let me explain. CFG80211 provides a netlink api called NL80211 which is
favorable over WEXT api. In user-space the iw tool is replacing iwconfig
and iwlist. Also wpa_supplicant has support for both wext and nl80211.
CFG80211_WEXT basically provides an adaptation/compatibility layer that
allows user-space tools to interact with cfg80211 drivers. However, it
is intended to be phased out so I would not recommend putting it in a
defconfig.
