Currently kernel only support setting the hw time stamping policy
through ioctl,now add a method to check which packets(Outgoing and
Incoming) are time stamped by nic.
Add this to igb_get_ts_info, we can query
one line, I have to move the
switch out of else judegment.
I test it on I350 and 82576NS nics and it works as expect.
Could help reviewing it again ? Any comments would be appreciated.

the type of rw to bool or define a new enum, then convert the if to
