I read about the MSI interrupt handling for FreeBSD, and I don't know if there's a way to split the interrupt request for each bce's Rx and Tx, which means a total of four IRQs, and eventually four cores (or 4 CPU) for the transactions. With this way, the IDLE processors would be utilized. Other ways how I can maximize the use of the IDLE CPUs? Thanks, Won
