[src/trunk]: src/sys/dev/pci/ixgbe - Count "Total Packets Missed" by evcnt(9)
details: https://anonhg.NetBSD.org/src/rev/6129cf92225c
branches: trunk
changeset: 353696:6129cf92225c

description:
- Count "Total Packets Missed" by evcnt(9)
- Call evcnt_attach_dynamic()/detach() for stats->mngpdc
(Management Packets Dropped).
- Make stats->rnbc (Receive No Buffers) evcnt(9). Only 82598 has this register.
- Set RQSMR, TQSM (or TQSMR on 82598) to count qprc, qptc, qbrc, qbtc and qprdc
in each queue counter. Without this change, all queue's counts are counted in
queue 0's. Even if with this change, only MPC[0] is counted and other MPCs
are not counted.
