wpa_supplicant deauthentication frames

[Hector Akamine]

Hello,
In order to do some testing, I commented out the
wpa_drv_deauthenticate() call inside wpa_supplicant_deauthenticate()
(in wpa_supplicant.c), to force wpa_supplicant not to send
deauthentication frames on disconnection (for example when killing the
wpa_supplicant process), but I am still getting deauthentication
frames from the STA. Is there any other part of the code that control
the sending of these frames?
I am using a recent commit from git, driver is nl80211 (ath9k)

Thank you,
Hector
