cxgb4: Add HW timesptamp support for RX
Adds support for ethtool get time stamp ioctl, which is used by
tcpdump to get the supported time stamp types
eg: tcpdump -i eth5 -J
Time stamp types for eth5 (use option -j to set):
host (Host)
adapter_unsynced (Adapter, not synced with system time)
Adds support for adapter unsynced mode, by adding SIOCSHWTSTAMP support
in driver.
