commit feb7d387a6cf6c1ec66d4a2b6d4b2cc52309876e upstream.
In order to specify that the mlxsw spectrum driver needs additional headroom for packets, there have been use of the hard_header_len field of the netdevice struct.
This commit changes that to use needed_headroom instead, as this is the correct way to do that.
