[PATCH] virtio-net: Update the max_tx_vq description

[Akihiko Odaki <akihiko.odaki@daynix.com>]

The previous description said:
> A driver sets \field{max_tx_vq} to inform a device how many transmit
> virtqueues it may use (transmitq1\ldots transmitq \field{max_tx_vq}).

However, it also controls how many receive virtqueues a device MAY use.
Copy the description of the virtqueue_pairs field of struct
virtio_net_ctrl_mq_pairs_set, which also has the identical semantics, to
clarify that.

 Field \field{indirection_table} is an array of receive virtqueues ids.
 
-A driver sets \field{max_tx_vq} to inform a device how many transmit virtqueues it may use (transmitq1\ldots transmitq \field{max_tx_vq}).
+Field \field{max_tx_vq} specifies the number of the transmit and receive queues

 Fields \field{hash_key_length} and \field{hash_key_data} define the key to be used in hash calculation.
