  const u8 * ie;

};
```

## MEMBERS

ssid

The SSID, will always be non-null.

bssid

Fixed BSSID requested, maybe be **NULL**, if set do not search for IBSSs with a different BSSID.

chandef

defines the channel to use if no other IBSS to join can be found

ie

information element(s) to include in the beacon

ssid\_len

The length of the SSID, will always be non-zero.

ie\_len

length of that

beacon\_interval

beacon interval to use

basic\_rates

bitmap of basic rates to use when creating the IBSS

channel\_fixed

The channel should be fixed -- do not search for IBSSs to join on other channels.

privacy

this is a protected network, keys will be configured after joining

control\_port

whether user space controls IEEE 802.1X port, i.e., sets/clears **NL80211\_STA\_FLAG\_AUTHORIZED**. If true, the driver is required to assume that the port is unauthorized until authorized by user space. Otherwise, port is marked authorized by default.

userspace\_handles\_dfs

whether user space controls DFS operation, i.e. changes the channel when a radar is detected. This is required to operate on DFS channels.

mcast\_rate\[IEEE80211\_NUM\_BANDS\]

per-band multicast rate index + 1 (0: disabled)

ht\_capa

HT Capabilities over-rides. Values set in ht\_capa\_mask will be used in ht\_capa. Un-supported values will be ignored.

ht\_capa\_mask

The bits of ht\_capa which are to be used.

## DESCRIPTION

This structure defines the IBSS parameters for the **join\_ibss** method.
