ehea: Remove num_tx_qps module option
The num_tx_qps module option allows a user to configure a different number of tx and rx queues. Now the networking stack is multiqueue aware it makes little sense just to enable the tx queues and not the rx queues so remove the option. v3: [cascardo] fixed conflict with get_stats change Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
