* | timestamping: fix example buildRandy Dunlap2010-03-152-7/+14
|/ | | | | | | | | | | | Fix Makefiles so that Documentation/networking/timestamping/timestamping.c will build when using the CONFIG_BUILD_DOCSRC kconfig option. (timestamping.c does not build currently with its simple Makefile.) Also fix printf format warnings.

* net: new user space API for time stamping of incoming and outgoing packetsPatrick Ohly2009-02-153-0/+540
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.
