-Subject: net: cadence: macb: Enable software IRQ coalescing by default
-
-From: Sean Anderson <sean.anderson@linux.dev>
-
-commit d57f7b45945ac0517ff8ea50655f00db6e8d637c upstream.
-
-This NIC doesn't have hardware IRQ coalescing. Under high load,
-interrupts can adversely affect performance. To mitigate this, enable
-software IRQ coalescing by default. On my system this increases receive
-throughput with iperf3 from 853 MBit/sec to 934 MBit/s, decreases
-interrupts from 69489/sec to 2016/sec, and decreases CPU utilization
-from 27% (4x Cortex-A53) to 14%. Latency is not affected (as far as I
-can tell).
