IEEE80211_REQUEST_SM(9) Advanced driver interface IEEE80211_REQUEST_SM(9)NAME
ieee80211_request_smps - request SM PS transition
SYNOPSIS
void ieee80211_request_smps(struct ieee80211_vif * vif, enum ieee80211_smps_mode smps_mode);
ARGUMENTS
vif
struct ieee80211_vif pointer from the add_interface callback.
smps_mode
new SM PS mode
DESCRIPTION
This allows the driver to request an SM PS transition in managed mode. This is useful when the driver has more information than the stack
about possible interference, for example by bluetooth.

MEMBERS
flags
configuration flags defined above
power_level
requested transmit power (in dBm)
dynamic_ps_timeout
The dynamic powersave timeout (in ms), see the powersave documentation below. This variable is valid only when the CONF_PS flag is set.
max_sleep_period
the maximum number of beacon intervals to sleep for before checking the beacon for a TIM bit (managed mode only); this value will be
only achievable between DTIM frames, the hardware needs to check for the multicast traffic bit in DTIM beacons. This variable is valid
only when the CONF_PS flag is set.
listen_interval
listen interval in units of beacon interval
ps_dtim_period
The DTIM period of the AP we're connected to, for use in power saving. Power saving will not be enabled until a beacon has been
received and the DTIM period is known.
long_frame_max_tx_count
Maximum number of transmissions for a "long" frame (a frame not RTS protected), called "dot11LongRetryLimit" in 802.11, but actually
means the number of transmissions not the number of retries
short_frame_max_tx_count
Maximum number of transmissions for a "short" frame, called "dot11ShortRetryLimit" in 802.11, but actually means the number of
transmissions not the number of retries
channel
the channel to tune to
channel_type
the channel (HT) type
smps_mode
spatial multiplexing powersave mode; note that IEEE80211_SMPS_STATIC is used when the device is not configured for an HT channel
DESCRIPTION
This struct indicates how the driver shall configure the hardware.
