device: Add callback for set interface rx-mode
- When the interface rx-mode is changed via CLI, the corresponding device may want to know about it and to reset the driver. This patch is to add the callback. - In the function vnet_hw_interface_set_rx_mode, it appears it is missing a line hw->rx_mode_by_queue[queue_id] = mode because the function is checking if the new mode is the same as hw->rx_mode_by_queue which is initialized to POLLING. So if the function is called to change the mode to interrupt, it just returns without doing anything. This is the check that I am talking about in the same function. if (hw->rx_mode_by_queue[queue_id] == mode) return 0; Change-Id: Iaca2651c43e0ae3fda6fd8dc128e247b0851cc65 Signed-off-by: Steven <sluong@cisco.com>
