From: Yotam Gigi <yotamg@xxxxxxxxxxxx> 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.
