usbeth: asix: Do a fast init if link already established
The Asix driver takes the link down during init() and then brings it back up.
This commit changes this so that if a link has already been established
successfully we simply check that the link is still good.
This reduces the delay between successive network commands.
TEST=bootp; tftp ... - see that delay is now shorter than before.
Change-Id: I044e6d12f6c175a87ee3c93bf874b497f9379c3e
BUG=chromium-os:14082
TEST=run U-boot; usb start; bootp; bootp
See that second bootp happens quickly and link stays up.
