[ECOS] N00blet question on networking

[Chuck McManis <ecos@mcmanis.com>]

Ok, so I have redboot working. Further I can build a libtarget.a with a 
basic set of options, I tried the simple program to get data from the 
console and echo it back, and I can boot redboot, 'load -h <my server> 
simple' and 'go' to run it. All's cool.

So I used ecosconfig to add in CYGPKG_NET and FREEBSD_STACK and ETH_DRIVERS
(actually there was a point where I had no conflicts but a couple of 
ethernet driver files were missing, its a CDL bug but I've not assured 
myself that I know enough about what I'm doing to call it a bug outright 
yet ;-)

Now I can build the httpd1.c test and when I run it this is what I get:
----------------------------------------------------

[eth_drv_ioctl] Warning: Driver can't set multi-cast mode

----------------------------------------

Ok, but when I do this, there doesn't seem to be any way to talk to my 
target board. Eventually it prints :

BOOTP/DHCP failed on eth0
[eth_drv_ioctl] Warning: Driver can't set multi-cast mode
[eth_drv_ioctl] Warning: Driver can't set multi-cast mode

Which seems unusual given that DHCP worked fine for Redboot.

So here are some questions:

What should this test print when it works? Should I be able to ping my 
target after using init_all_network_interfaces() ? What is different 
between Redboot's use of my driver and ECOS's use of the driver?
