net: bcmgenet: fix software maintained statistics
Commit 44c8bc3ce39f ("net: bcmgenet: log RX buffer allocation and RX/TX dma failures") added a few software maintained statistics using BCMGENET_STAT_MIB_RX and BCMGENET_STAT_MIB_TX. These statistics are read from the hardware MIB counters, such that bcmgenet_update_mib_counters() was trying to read from a non-existing MIB offset for these counters. Fix this by introducing a special type: BCMGENET_STAT_SOFT, similar to BCMGENET_STAT_NETDEV, such that bcmgenet_get_ethtool_stats will read from the software mib. Fixes: 44c8bc3ce39f ("net: bcmgenet: log RX buffer allocation and RX/TX dma failures") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
