+AF_PACKET receive support

+When VLAN offload is enabled on the NIC Linux will not deliver the VLAN tag
+in the data returned by recv. Instead, it delivers the VLAN TCI in a control
+message. Python 2.x doesn't have built-in support for recvmsg, so we have to
+use ctypes to call it. The recv function exported by this module reconstructs
+the VLAN tag if it was offloaded.
