MEMBERS
conf
struct ieee80211_conf, device configuration, don't use.
wiphy
This points to the struct wiphy allocated for this 802.11 PHY. You must fill in the perm_addr and dev members of this structure using
SET_IEEE80211_DEV and SET_IEEE80211_PERM_ADDR. Additionally, all supported bands (with channels, bitrates) are registered here.
rate_control_algorithm
rate control algorithm for this hardware. If unset (NULL), the default algorithm will be used. Must be set before calling
ieee80211_register_hw.
priv
pointer to private area that was allocated for driver use along with this structure.
flags
hardware flags, see enum ieee80211_hw_flags.
extra_tx_headroom
headroom to reserve in each transmit skb for use by the driver (e.g. for transmit headers.)
channel_change_time
time (in microseconds) it takes to change channels.
vif_data_size
size (in bytes) of the drv_priv data area within struct ieee80211_vif.
sta_data_size
size (in bytes) of the drv_priv data area within struct ieee80211_sta.
queues
number of available hardware transmit queues for data packets. WMM/QoS requires at least four, these queues need to have configurable
access parameters.
max_listen_interval
max listen interval in units of beacon interval that HW supports
max_signal
Maximum value for signal (rssi) in RX information, used only when IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB
max_rates
maximum number of alternate rate retry stages
max_rate_tries
maximum number of tries for each stage
DESCRIPTION
This structure contains the configuration and hardware information for an 802.11 PHY.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.

Hello for all,
I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
It doesn't matter the amount of used memory as application is intended to perform many transactions; rather, what I want to achieve is to... (2 Replies)
