Navdeep Parhar 27d1c65e8e cxgb(4): add knob to get packet timestamps from the hardware. 
The T3 ASIC can provide an incoming packet's timestamp instead of its RSS hash.
The timestamp is just a counter running off the card's clock.  With a 175MHz
clock an increment represents ~5.7ns and the 32 bit value wraps around in ~25s.

# sysctl -d dev.cxgbc.0.pkt_timestamp
dev.cxgbc.0.pkt_timestamp: provide packet timestamp instead of connection hash

# sysctl -d dev.cxgbc.0.core_clock
dev.cxgbc.0.core_clock: core clock frequency (in KHz)
# sysctl dev.cxgbc.0.core_clock
dev.cxgbc.0.core_clock: 175000
