Navdeep Parhar a5eb009b49 cxgb: replace r273280 with a more comprehensive fix. 
Poll for link state when the link is down, even for interrupt capable
PHYs.

Allow PHYs to report a dubious "partial" link.  If this state is seen 3
consecutive times (each check is ~1s apart) then reset the PHY.  This is
a workaround for a situation where repeatedly toggling the link from the
peer gets the AEL2005 PHY into a state where it never establishes a PCS
block lock even when everything is in order.
