Modified Files: src/sys/dev/mii: makphy.c Log Message: QEMU e1000's PHY code doesn't implement page 0 register 15. Do workaround. - The BMSR register bit 8 (BMSR_EXTSTAT) denote the existence of page 0 register 15. qemu's e1000 sets BMSR_EXTSTAT but the access to register 15 fails. It doesn't conforms to the IEEE standard. Our makphy automatically check the existence of 1000BASE-T or 1000BASE-SX by accessing the register 15. If the access failed, neither 1000BASE-T nor 1000BASE-SX is set to the ability(mii_extcapabilities). Set EXTSR_1000TFDX and EXTSR_1000THDX if the access failed in the attach function. It's just a cosmetic change. It's not affected to the packet processing.
