[TG3]: Fix link problem on Dell's onboard 5906.
The bug is caused by code that always set
(TG3_FLAG_USE_MI_INTERRUPT | TG3_FLAG_USE_LINKCHG_REG) on all Dell's
onboard devices. With these 2 flags set, the link status is polled
by tg3_timer() and will only work when the PHY is set up to interrupt
the MAC on link changes. This breaks 5906 because the 5906 PHY does
not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs.
For correctness, only Dell's onboard 5701 needs these 2 flags to be
set. This change will fix the 5906 problem and will change other
Dell devices except 5700 and 5701 to use the more efficient
interrupt-driven link changes.
Update version to 3.77.
