* rndis_wlan: disable stall workaroundJussi Kivilinna2009-11-23
| | | | | | | | | Stall workaround doesn't work with bcm4320a devices like with bcm4320b. This workaround actually causes more stalls/device freeze on bcm4320a. Therefore disable stall workaround by default. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rndis_wlan: fix buffer overflow in rndis_query_oidJussi Kivilinna2009-11-23
| | | | | | | | | | | rndis_query_oid overwrites *len which stores buffer size to return full size of received command and then uses *len with memcpy to fill buffer with command. Ofcourse memcpy should be done before replacing buffer size. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rndis_wlan: handle NL80211_AUTHTYPE_AUTOMATICJussi Kivilinna2009-11-16
| | | | | | | | | | | rndis_wlan didn't know about NL80211_AUTHTYPE_AUTOMATIC and simple setup with 'iwconfig wlan essid no-encrypt' would fail (ENOSUPP). v2: use NDIS_80211_AUTH_AUTO_SWITCH instead of _OPEN. This will make device try shared key auth first, then open. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | Setting WPA keys with OID_802_11_ADD_KEY sometimes trigger instant media connect indication.

This is needed by rndis_wlan so that it can control rx queue and prevent received packets from being send forward before rndis_wlan receives and handles 'media connect'-indication.
