Add 64-bit counters for each impairment netem applies (delay, loss, ECN marking, corruption, duplication, reordering) and for skb allocation failures during enqueue. Exposed through TCA_STATS_APP as struct tc_netem_xstats. Counters increment when an impairment is occurs, independent of later events that may mask its on-wire effect. Added allocation_errors (similar to sch_fq) to account for when impairment could not be applied due to memory pressure, etc. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Link: https://patch.msgid.link/20260509171123.307549-6-stephen@networkplumber.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>
