From cb9eff097831007afb30d64373f29d99825d0068 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Thu, 12 Feb 2009 05:03:36 +0000 Subject: net: new user space API for time stamping of incoming and outgoing packets User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

+1000 Subject: m68k: merge the non-MMU and MMU versions of siginfo.h It is trivial to merge the non-MMU and MMU versions of siginfo.h. Without a single file "make headers_install" is broken for m68k (since each of the sub-varients of siginfo.h are not installed).
