Avoid multiple queues when MSI or MSI-X not available Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in the kernel. This will make number of tx and rx queues equal when MSI/X is not configured thus providing better performance. Signed-off-by: Bhavesh Davda Signed-off-by: Shreyas N Bhatewara Signed-off-by: David S.
