Pyun YongHyeon 6e854927d1 If RX lockup workaround is enabled, fxp(4) will periodically reset ... the controller to workaround silicon bug of i82557. Each reset will re-establish link which in turn triggers MII status change callback. The callback will try to reconfigure controller if the controller is not i82557 to enable flow-control. This caused endless link UP/DOWN when the workaround was enabled on non-i82557 controller. To fix the issue, apply RX lockup workaround only for i82557. Previously it blindly checked undocumented EEPROM location such that it sometimes enabled the workaround for other controllers. At this time, only i82557 is known to have the silicon bug. This fixes a regression introduced in r215906 which enabled flow control support for all controllers except i82557.
