ice: Add stats and ethtool support

This patch implements a watchdog task to get packet statistics from
the device.

This patch also adds support for the following ethtool operations:

ethtool devname
ethtool -s devname [msglvl N] [msglevel type on|off]
ethtool -g|--show-ring devname
ethtool -G|--set-ring devname [rx N] [tx N]
ethtool -i|--driver devname
ethtool -d|--register-dump devname [raw on|off] [hex on|off] [file name]
ethtool -k|--show-features|--show-offload devname
ethtool -K|--features|--offload devname feature on|off
ethtool -P|--show-permaddr devname
ethtool -S|--statistics devname
ethtool -a|--show-pause devname
ethtool -A|--pause devname [autoneg on|off] [rx on|off] [tx on|off]
ethtool -r|--negotiate devname
