When one or more packets are received, an interrupt happens. The interrupts

are not queued so the driver has to scan all the descriptors in the ring during

the receive process.

This is based on NAPI so the interrupt handler signals only if there is work to be

done, and it exits.

This is based on NAPI so the interrupt handler signals only if there is work

Then the poll method will be scheduled at some future point.

The incoming packets are stored, by the DMA, in a list of pre-allocated socket

buffers in order to avoid the memcpy (Zero-copy).



4.3) Timer-Driver Interrupt

Instead of having the device that asynchronously notifies the frame receptions, the

driver configures a timer to generate an interrupt at regular intervals.

Based on the granularity of the timer, the frames that are received by the device

will experience different levels of latency. Some NICs have dedicated timer

device to perform this task. STMMAC can use either the RTC device or the TMU

channel 2  on STLinux platforms.
