TX limitations
--------------
-Kernel processing usually involves validation of the message received by
-user-space, then processing its contents. The kernel must assure that
-userspace is not able to modify the message contents after they have been
-validated. In order to do so, the message is copied from the ring frame
-to an allocated buffer if either of these conditions is false:
-
-- only a single mapping of the ring exists
-- the file descriptor is not shared between processes
-
-This means that for threaded programs, the kernel will fall back to copying.
+As of Jan 2015 the message is always copied from the ring frame to an
+allocated buffer due to unresolved security concerns.
+See commit 4682a0358639b29cf ("netlink: Always copy on mmap TX.").

option IP_PKTINFO simultaneously.
+SOF_TIMESTAMPING_OPT_TSONLY:
+
+ Applies to transmit timestamps only. Makes the kernel return the
+ timestamp as a cmsg alongside an empty packet, as opposed to
+ alongside the original packet. This reduces the amount of memory
+ charged to the socket's receive budget (SO_RCVBUF) and delivers
+ the timestamp even if sysctl net.core.tstamp_allow_data is 0.
+ This option disables SOF_TIMESTAMPING_OPT_CMSG.

+
+New applications are encouraged to pass SOF_TIMESTAMPING_OPT_ID to
+disambiguate timestamps and SOF_TIMESTAMPING_OPT_TSONLY to operate
+regardless of the setting of sysctl net.core.tstamp_allow_data.
+
+An exception is when a process needs additional cmsg data, for
+instance SOL_IP/IP_PKTINFO to detect the egress network interface.
+Then pass option SOF_TIMESTAMPING_OPT_CMSG. This option depends on
+having access to the contents of the original packet, so cannot be
