It stays at Count=22 as I rebind to nvme.

```
06:00.0 Non-Volatile memory controller [0108]: Intel Corporation SSD Pro
7600p/760p/E 6100p Series [8086:f1a6] (rev 03) (prog-if 02 [NVM Express])
...
        Capabilities: [b0] MSI-X: Enable+ Count=22 Masked-
                Vector table: BAR=0 offset=00002000
                PBA: BAR=0 offset=00002100
...
        Kernel driver in use: nvme
```

It continues to stay at Count=22 after resetting
echo 1 | tee /sys/bus/pci/devices/0000:06:00.0/reset
```

After reboot it comes back to Count=16
