Mike Marciniszyn 8482d5d1bc IB/qib: Eliminate 64-bit jiffies use
The qib driver makes use of the the 64-bit jiffies API.

Code inspection reveals that that version of the API is not really
required.  This patch converts to use the "normal" jiffies.

Mitko Haralanov dde05cbdf8 IB/qib: Hold links until tuning data is available
Hold the link state machine until the tuning data is read from the
QSFP EEPROM so correct tuning settings are applied before the state
machine attempts to bring the link up.  Link is also held on cable
unplug in case a different cable is used.
