For 82550 controllers this change restores CPUSaver microcode loading. Due to silicon bug on 82550 and 82550C with server extension, these controllers seem to require CPUSaver microcode to receive fragmented UDP datagrams. However the microcode shouldn't be used on client featured 82550C as it locks up the controller. In addition, client featured 82550C does not have the silicon bug. Also clear temporary memory used for microcode loading since the same memory area is used for other commands. While I'm here use 82550C in probe message instead of generic 82550. Reported by: Andreas Longwitz incore de> Tested by: Andreas Longwitz incore de> r233586: Load entire EEPROM contents in device attach time and verify whether the checksum of EEPROM is valid or not. Because driver heavily relies on EEPROM information when it selectively enables features/workarounds, it would be helpful to know whether driver sees valid EEPROM. While I'm here remove all other EEPROM accesses since the entire EEPROM is loaded at device attach time. r233587: Remove unnecessary #if as the software workaround for PCI protocol violation should be activated unless the system is cold-booted after updating EEPROM. The PCI protocol violation happens only when established link is 10Mbps so the workaround should be updated whenever link state change is detected. Previously the workaround was activated only when user checks current media status with ifconfig(8). END
