0x003dfd94 - eth0 -
0x003dfdb0 - eth0 - 10.0.0.7
indx(eth0) = 1
index(eth0) = 1/eth0
Notice how there are two interfaces named "eth0" and the second
one is the one with the IP address? The SIOCGIFADDR always
returns the address from the first interface (which doesn't
_have_ an address, so the structure is all 0's).
There must be something wrong about the way I'm initializing
the stack things. When I let DHCP do it, I get different
results:
0x003dfd94 - eth0 - 10.0.0.7
0x003dfdcc - lo0 - 127.0.0.1
indx(eth0) = 1
index(eth0) = 1/eth0
Moving to the new network stack sure has proven to be more of a
pain than I anticipated...
