ieee80211_alloc_hw(9) [centos man page]

IEEE80211_ALLOC_HW(9)					  The basic mac80211 driver inte				     IEEE80211_ALLOC_HW(9)

NAME
ieee80211_alloc_hw - Allocate a new hardware device SYNOPSIS
struct ieee80211_hw * ieee80211_alloc_hw(size_t priv_data_len, const struct ieee80211_ops * ops); ARGUMENTS
priv_data_len length of private data ops callbacks for this device DESCRIPTION
This must be called once for each hardware device. The returned pointer must be used to refer to this device when calling other functions. mac80211 allocates a private data area for the driver pointed to by priv in struct ieee80211_hw, the size of this area is given as priv_data_len. RETURN
A pointer to the new hardware device, or NULL on error. AUTHOR

NAME
ieee80211_sta_block_awake - block station from waking up SYNOPSIS
void ieee80211_sta_block_awake(struct ieee80211_hw * hw, struct ieee80211_sta * pubsta, bool block); ARGUMENTS
hw the hardware pubsta the station block whether to block or unblock DESCRIPTION
Some devices require that all frames that are on the queues for a specific station that went to sleep are flushed before a poll response or frames after the station woke up can be delivered to that it. Note that such frames must be rejected by the driver as filtered, with the appropriate status flag. This function allows implementing this mode in a race-free manner. To do this, a driver must keep track of the number of frames still enqueued for a specific station. If this number is not zero when the station goes to sleep, the driver must call this function to force mac80211 to consider the station to be asleep regardless of the station's actual state. Once the number of outstanding frames reaches zero, the driver must call this function again to unblock the station. That will cause mac80211 to be able to send ps-poll responses, and if the station queried in the meantime then frames will also be sent out as a result of this. Additionally, the driver will be notified that the station woke up some time after it is unblocked, regardless of whether the station actually woke up while blocked or not. AUTHOR
