[PATCH] 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 5701 on Dell systems 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 3.75.2.
