SendTxFeedback?

[Marcelo Tosatti]

Hi Ronak,

It is my understanding that given a packet transmission failure, the
driver attempts to send the failed packet back to the upper layers (what
is called "tx feedback"), if radiotap mode is enabled.

At this level, the packet transmission can only fail due to a removed
card or failure in the USB transfer.

I fail to see any use for such an "error reporting", can you explain
what is going on?

Thanks

PS: do you have any numbers for the savings gained by enabling the power
mode saving mode, when idle?
