* Queue monitoring.
|
||
|
|
*
|
||
|
|
* The feature allows monitoring the DHD queue utilization to get the percentage of a time period
|
||
|
|
* where the number of pending packets is above a configurable theshold.
|
||
|
|
* Right now, this is used by a server application, interfacing a Miracast Video Encoder, and
|
||
|
|
* doing IOVAR "qtime_percent" at regular interval. Based on IOVAR "qtime_percent" results,
|
||
|
|
* the server indicates to the Video Encoder if its bitrate can be increased or must be decreased.
|
||
|
|
* Currently, this works only with P2P interfaces and with PROP_TXSTATUS. There is no need to handle
|
||
|
|
* concurrent access to the fieds because the existing concurrent accesses are protected
|
||
|
|
* by the PROP_TXSTATUS's lock.
