> An issue is found that DCB cannot be configured on ixgbe
> NICs. It's said the TX queue number is not right.
> On ixgbe the max TX queue number is not fixed, it depends
> on the multi-queue mode. The API rte_eth_dev_configure
> should be used to configure this mode. But the input of
> this API includes TX queue number. The problem is before
> the mode is configured, we cannot decide the TX queue
> number.
> 
> This patch adds an API to configure RX & TX multi-queue mode
> separately. After the mode is configured, the max RX & TX
> queue number is decided. Then we can set the appropriate
> RX & TX queue number.
