| IWEVREGISTERED | Discovered a new node (AP mode) | not support (AP mode はサポートしてない) |
| IWEVEXPIRED | Expired a node (AP mode) | not support (AP mode はサポートしてない) |
New Access Point/Cell address
The interface has joined a new Access Point or Ad-Hoc Cell, or lost its
association with it. This is the same MAC address that is reported by
iwconfig.
Scan request completed
A scanning request has been completed, results of the scan are available
(see iwlist).
Tx packet dropped
A packet directed at this address has been dropped because the interface
believes this node doesn't answer anymore (usually maximum of MAC level
retry exceeded). This is usually an early indication that the node may
have left the cell or gone out of range, but it may be due to fading or
excessive contention.
Custom driver event
Event specific to the driver. Please check the driver documentation.
Registered node
The interface has successfully registered a new wireless client/peer.
Will be generated mostly when the interface act as an Access Point (mode
master).
Expired node
The registration of the client/peer on this interface has expired. Will
be generated mostly when the interface act as an Access Point (mode mas-
ter).
Spy threshold crossed
The signal strength for one of the address in the spy list went under the
low threshold or went above than the high threshold.TODO 基本的には、signal quality,signal level, noise なんかの表示。Thresholdも指定できるらしい。
TODO 実装予定コマンド
| command | direction | description |
|---|---|---|
| connect confirm | get | 無線の接続状態の取得 |
| driver version | get | driverのversionの取得 |
| firmware version | get | firmwareのversionの取得 |
| preamble | set&get | preambleの取得、設定 |
| disconnect | set | 強制的に、接続状態を切り替える |
| power management ? | set&get | iwconfig の形式で対応できなかったら |
| data read | get ? | このコマンドで実装できるか不明 |
| data write | set ? | このコマンドで実装できるか不明 |
ifconfig みたいな奴。パラメータ等の設定など。
