Two network interfaces

[Leon Pollak]

Hello, all.

I have the following situation with 2 network interfaces been initialized.

The first interface is fully functional in HW and SW, but the second 
controller which is connected to the PHY via MII has no physical connection 
to the network and PHY therefore does not have link.

When I initialize the only first IF and give the application to run - 
everything is OK: I can ping the box without any problem.

If I only add the second interface to the chain, the first stops functioning - 
no replies to ping and arp and I see the "Still waiting for mbuf cluster" 
message printed periodically.

I am not able to have the second interface physically connected in some 2-3 
weeks. But I should be ready to work with it when it will be connected.

Therefore I just wanted to know: if such a behavior may be caused by the 
second "faulty" interface or I need to work hard searching for a bug in the 
driver?

Many thanks ahead.

P.S. May be this is helpfull - rtems_bsdnet_ifconfig structures are filled as:
