Many fixes from Bill Paul:
Smack the netboot program around so that it will allow the user to
specify mount options. [So that you can boot from a privileged port]
Change the default boot image name in netboot to /kernel, then strip
the leading slash when actually going out to get the NFS file handle.
Added support for 3Com 3c503 cards. Also added another command to
the (trans) that allows you to switch the 3Com's on-board transceiver
on and off. (ether.c, ether.h, bootmenu.c)
Modified the Makefile to support new compile-time options for 3c503
cards:
-DINCLUDE_3COM Include support for 3c503
-D_3COM_BASE=0x300 Define 3c503 base i/o address (if not
specified, 0x300 is the default)
-D_3COM_USE_AUI Disable the 3c503's transceiver by
default (without this flag the transceiver
is on by default)
