realtek interface not working

[Sreenath Battalahalli]

Hi 

I got  a new laptop (Acer E5-573) that has a Realtek 1Gbps adapter.
ifconfig after booting does not list re0 interface.

Here are relevant lines from dmesg:

re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F/G PCIe Gigabit Ethernet> port 0x3000-0x3
0ff mem 0xb0604000-0xb0604fff,0xb0600000-0xb0603fff irq 18 at device 0.0 on pci2
re0: Using 1 MSI-X message
re0: turning off MSI enable bit.
re0: ASPM disabled
re0: Chip rev. 0x54000000
re0: MAC rev. 0x00100000
re0: Unknown H/W revision: 0x54000000
device_attach: re0 attach returned 6

Looks like this hardware is not supported by the driver.

Freebsd version is 10.2 amd64 

any help if getting this to work appreciated.

thanks,
Sreenath
