The content doesn't change over multiple show invocations, so the behavior shouldn't change at all for the attribute and seq_file handles seeking and partial reads correctly. No idea what could go wrong there. It probably was reading /sys/devices/BLAHBLAH/net/NETIF/broadcast file. Can you please locate the file and do "ls -l" and "cat" on it? If that looks normal, can you please strace the network interface config program / script / whatever? BTW, what are you running on the system?
