be2net: use stats-sync to read/write 64-bit stats
64-bit stats in be2net are written/read as follows using the stats-sync
interface for safe access in 32-bit archs:
64-bit sync writer reader
stats
------------------------------------------------------------------------------
tx_stats tx_stats->sync be_xmit be_get_stats64,
ethtool
tx-compl tx_stats->sync_compl tx-compl-processing ethtool
rx-stats rx_stats->sync rx-compl-processing be_get_stats64,
ethtool,
eqd-update
This patch is based on Stephen Hemminger's earlier patch on the same issue...
