We are using FNET Stack for MCF52259 based application.


Some information is required to optimize my application, I need to clarify following.


1.) Multiple Ethernet RX buffer and Tx Buffer are used. Why it is required and its benefit?

2.) After doing some brief study of FNET stack,it appears that after receiving the Ethernet Frame some software interrupt is generated for ARP and IP.


Please know me , How software interrupt is executing while Vector number of SW interrupts are  out of Vector table  or  there is other mechanism used  to  slice f Ethernet Receive frame interrupt.
