From efe074c2cc1c67021481f56ba87cc61d1ab03e33 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 16 Mar 2020 19:12:49 -0700 Subject: net_sched: add qdisc_watchdog_schedule_range_ns() Some packet schedulers might want to add a slack when programming hrtimers. This can reduce number of interrupts and increase batch sizes and thus give good xmit_more savings. This commit adds qdisc_watchdog_schedule_range_ns() helper, with an extra delta_ns parameter. Legacy qdisc_watchdog_schedule_n() becomes an inline passing a zero slack. Signed-off-by: Eric Dumazet Signed-off-by: David S.
