[PATCH net 0/2] net: ntb_netdev: Fix RX statistics accounting

[Koichiro Den]

Hi,

This series addresses Jakub's comment on ntb_netdev RX statistics
accounting:
https://lore.kernel.org/r/20260818092938.4121c220@xxxxxxxxxx/

It fixes the double counting and also the related packet/byte accounting
on RX refill failure.

Notes:
- No ordering dependency on the TX completion/error handling series,
  which is currently awaiting review. Either series can go first.
  https://patchwork.kernel.org/project/netdevbpf/cover/20260817053519.4135287-1-den@xxxxxxxxxxxxx/
- Once both series land, I plan to post one follow-up patch to net for
  the multi-queue stats race introduced by commit 24d9e73c7e00 ("net:
  ntb_netdev: Support ethtool channels for multi-queue"). My plan is to
  move packet/byte/drop counters to core-managed per-CPU stats and use
  DEV_STATS_INC() for the remaining slow-path counters. IMO this is
  lower severity and better done after the TX/RX changes settle.

Best regards,
Koichiro
