kernel: use skb_cow_head() to deal with cloned skbs
We need to ensure there is enough headroom to push extra header, but we also need to check if we are allowed to change headers. skb_cow_head() is the proper helper to deal with this. Fixes Ethernet<->WiFi bridge for Raspberry Pi and probably other devices. Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
