This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.
Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).
This change effectively reverts the following CVS commit:
sys/boot/common/dev_net.c
revision 1.7
date: 2000/05/13 15:40:46; author: dfr; state: Exp; lines: +2 -1
Only probe network settings on the first open of the network device.
The alpha firmware takes a seriously long time to open the network device
the first time.
Also suppress excessive output while netbooting via loader, unless debugging.
While there, make sys/boot/uboot more style(9) compliant.
