Merge branch 'net-add-functionality-to-net-core-byte-packet-counters-and-use-it-in-r8169'
Heiner Kallweit says: ==================== net: add functionality to net core byte/packet counters and use it in r8169 This series adds missing functionality to the net core handling of byte/packet counters and statistics. The extensions are then used to remove private rx/tx byte/packet counters in r8169 driver. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
