Krzysztof Kazimierczak cc5b5d3565 xsk: Check if a queue exists during umem setup ... In the xdp_umem_assign_dev() path, the xsk code does not check if a queue for which umem is to be created exists. It leads to a situation where umem is not assigned to any Tx/Rx queue of a netdevice, without notifying the stack about an error. This affects both XDP_SKB and XDP_DRV modes - in case of XDP_DRV_ZC, queue index is checked by the driver. This patch fixes xsk code, so that in both XDP_SKB and XDP_DRV mode of AF_XDP, an error is returned when requested queue index exceedes an existing maximum.
