Subject: [PATCH net-next 1/7] net: hibmcge: Add dump statistics supported in this module
The driver supports many hw statistics. This patch supports
dump statistics through ethtool_ops and ndo.get_stats64().
The type of statistics register is u32,
and the type of driver statistics u64.
To prevent the statistics register from overflowing,
the driver dump the statistics every 5 minutes.
