commit 251d41c58b765f00d73b1b4230cad256e25f2735 upstream.
In order to specify that the mlxsw switchx2 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.
