[BitVisor-devel:64] device addition(BCM5720) and cannot link-up (like as PRO/1000)

[Iori YONEJI]

Hello, I'm Iori Yoneji at Univ.Tsukuba.

I have good news and bad news (question).

Good one. I just added a device ID of BCM5720 into device list.
I have confirmed that it works with "tty" and "virtio" options as the
case with PRO/1000.

Bad one. However, both of the two kind of NICs (including BCM5720
I218-LM and I350-T2) could not been used under linux.
These NICs can be camouflaged as virtio_pci device(checked with lspci
-vvvvx), still, can not be linked-up.
By "ip" command, the NIC state are printed as UNKNOWN.

The only change in the code(against 72f66eb) is device addition
(below). Plus, I changed defconfig (as second below).
If someone (I'm expectin' for Eiraku-san :p) know about this issue and
fix, I'm very pleased to be informed about that.
