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: 4cfd5779 ("taprio: Add support for txtime-assist mode") Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Signed-off-by: David S.
