1. A method for dropping lower priority packets that are slated for transmission over a wireless communication medium, comprising:

  • receiving a plurality of packets to be transferred over the wireless communication medium;

    storing the plurality of packets in a plurality of priority queues in a fixed shared memory space based on an order in which the plurality of packets are received and based on priorities associated with the plurality of packets;

    signaling an interrupt when a packet threshold is exceeded in one of the plurality of priority queues; and

    in response to the interrupt being signaled, dropping a portion of the plurality of packets stored in a at least two of the plurality of priority queues to make available additional memory space in the fixed shared memory space.
