Huntington adds further to the NIC-type-specific statistics, as it has different MAC blocks from Falcon/Siena. All NIC types still provide most statistics by DMA, and use little-endian byte order. Therefore: 1. Add some general utility functions for reporting hardware statistics, efx_nic_describe_stats() and efx_nic_update_stats(). 2. Add an efx_nic_type::describe_stats operation to get the number and names of statistics, implemented using efx_nic_describe_stats() 3. Change efx_nic_type::update_stats to store the core statistics (struct rtnl_link_stats64) or full statistics (array of u64) in a caller-provided buffer. Use efx_nic_update_stats() to aid in the implementation. 4. Rename struct efx_ethtool_stat to struct efx_sw_stat_desc and EFX_ETHTOOL_NUM_STATS to EFX_ETHTOOL_SW_STAT_COUNT. 5. Remove efx_nic::mac_stats and struct efx_mac_stats. Signed-off-by: Ben Hutchings --- Reading git-diff-tree failed
