Or should I call the Mac::sendUp(Packet* p)? And where I should call it?
- before if(tx_active_ && hdr->error() == 0) ?
- before if(rx_state_ == MAC_IDLE)?
- or at the end of the method?
The method Mac802_11::recv is copied below. Thanks again!

*/

/*

/*
* Handle incoming packets.

* We just received the 1st bit of a packet on the network

/*
* If the interface is currently in transmit mode, then
