taprio: Fix dropping packets when using taprio + ETF offloading
When using taprio offloading together with ETF offloading, configured like this, for example: $ tc qdisc replace dev $IFACE parent root handle 100 taprio \ num_tc 4 \ map 2 2 1 0 3 2 2 2 2 2 2 2 2 2 2 2 \ queues 1@0 1@1 1@2 1@3 \ base-time $BASE_TIME \ sched-entry S 01 1000000 \ sched-entry S 0e 1000000 \ flags 0x2 $ tc qdisc replace dev $IFACE parent 100:1 etf \ offload delta 300000 clockid CLOCK_TAI During enqueue, it works out that the verification added for the "txtime" assisted mode is run when using taprio + ETF offloading, the only thing missing is initializing the 'next_txtime' of all the cycle entries. (if we don't set 'next_txtime' all packets from SO_TXTIME sockets are dropped) Fixes: 4cfd5779bd6e ("taprio: Add support for txtime-assist mode") Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Signed-off-by: David S.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
