Patch 1 fixes an issue which causes TX timeouts due to HW detection of an illegal descriptor. This happens when receiving header-only packets with header split enabled - this produces an SKB with a zero-length fragment. Patch 2 prevents a kernel NULL pointer dereference by stubbing the PTP adjfine callback.
