This can cause the EQ to become full. So, while the device is not open, CQ must not be re-armed to prevent EQ entries. Signed-off-by: Sathya Perla Signed-off-by: David S.

This can cause tx compl processing to be scheduled on another cpu concurrently which can result in a panic. This if fixed by calling napi complete() after tx/mcc compl processing but before re-enabling interrupts (via a cq notify). Signed-off-by: Sathya Perla Signed-off-by: David S.
