Hi, I was going through the devn-mpc85xx source code, and I found that it does not utilize the transmit interrupts. It does not set the interrupt field of the Tx buffer descriptors, and hence no irq is raised when the transmission completes. Is this by design? Thanks, Rajat
Yes, this is by design to minimize interrupts. Every new transmit will reap transmitted buffers and return them to io-net. -----Original Message----- From: Rajat Jain [mailto:rajat.jain@infogain.com] Sent: Thursday, July 03, 2008 4:52 AM To: drivers-networking Subject: devn-mpc85xx not utilizing Tx IRQs Hi, I was going through the devn-mpc85xx source code, and I found that it does not utilize the transmit interrupts.
