The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.
This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.
Note: this patch was previously submitted many moons ago as:
usb: usbeth: asix: Do a fast init if link already established
That patch seens to have been lost or forgotten, so this is a rebased
version. It is tested on snow with a Asix USB dongle (Cisco).
