As the above comment in the code says, this is very\nunlikely to happen, but it's wrong anyway so let's fix it.\n\nI hit this issue because of a different bug that caused tx_queue to be\nNULL. If that happens, this is the error message that we get here:\n  BUG: unable to handle kernel NULL pointer dereference at 0000000000000020\n  [...]\n  RIP: 0010:efx_hard_start_xmit+0x153/0x170 [sfc]"
