Typically your driver is going to pass the packet back to lwIP
via a function like tcpip_input(...). Look at it just before that, and
maybe don't pass it in to lwIP.

Hi there,
My application requires to tag a small
codes to the lowest level of read routine to monitor a private non-standard
packet as soon as it arrives (I am using lwip+FreeRTOS+AVR32). preferable at the
interrupt that retrieves the data from the PHY: cature the special packet and
perform action immediately, but remove it from the queque so that lwip will not
waste time on it.
Any pointer to such path? Thanks
