Can anybody explain what purpose of unnamed interrupts of Mellanox ConnectX-5 cards? I am see 19 interrupts per card. I am mean last 16 is RX queue. What about first 3? Also I am see very high rate for irq287/irq306 -- is this good? # vmstat -i | grep -e ^int -e mlx interrupt total rate irq286: mlx5_core0 1 0 irq287: mlx5_core0 5135992 20 irq288: mlx5_core0 1 0 irq289: mlx5_core0 76408 0 irq290: mlx5_core0 43054 0 irq291: mlx5_core0 93826 0 irq292: mlx5_core0 39457 0 irq293: mlx5_core0 36141 0 irq294: mlx5_core0 65526 0 irq295: mlx5_core0 53399 0 irq296: mlx5_core0 120885 0 irq297: mlx5_core0 140690 1 irq298: mlx5_core0 193578 1 irq299: mlx5_core0 178332 1 irq300: mlx5_core0 75334 0 irq301: mlx5_core0 207118 1 irq302: mlx5_core0 108803 0 irq303: mlx5_core0 24356 0 irq304: mlx5_core0 26713 0 irq305: mlx5_core1 1 0 irq306: mlx5_core1 5136296 20 irq307: mlx5_core1 1 0 irq308: mlx5_core1 3634544 14 irq309: mlx5_core1 22860 0 irq310: mlx5_core1 564441 2 irq311: mlx5_core1 30503 0 irq312: mlx5_core1 115549 0 irq313: mlx5_core1 49815 0 irq314: mlx5_core1 10272 0 irq315: mlx5_core1 85875 0 irq316: mlx5_core1 134251 1 irq317: mlx5_core1 25151 0 irq318: mlx5_core1 73376 0 irq319: mlx5_core1 5879 0 irq320: mlx5_core1 39515 0 irq321: mlx5_core1 5390 0 irq322: mlx5_core1 22726 0 irq323: mlx5_core1 60408 0
