I am a newbie and this is my first post to this list.
In net/ipv4/ipconfig.c (I'm looking at linuxppc versions in 2.4 and 2.5 trees)
There is a comment describing an if statement. To me it seems that either the comment is wrong or the if statement is wrong. Which is it, or how am I misinterpreting?
The phrase "we have multiple network interfaces and no default was set" should correspond to something like (ic_first_dev->next && !ic_default), but there is no ic_default.
/*
* If the config information is insufficient (e.g., our IP address or
* IP address of the boot server is missing or we have multiple network
* interfaces and no default was set), use BOOTP or RARP to get the
* missing values.
*/
if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
(MAJOR(ROOT_DEV) == UNNAMED_MAJOR
&& root_server_addr == INADDR_NONE
&& ic_servaddr == INADDR_NONE) ||
#endif
ic_first_dev->next) {
How this affects me: I get to this point with three ethernet devices eth0,eth1,eth2 and would like to use the valid parameters in ic_myaddr et al for eth0 and leave the other two to be manually configured after boot time. But because there are multiple interfaces, ic_first_dev->next is not NULL so ic_dynamic gets called and DHCP is attempted for eth0 instead of using ic_myaddr et al.
So, what am I missing? Where am I supposed to "set a default" when I have multiple interfaces?
Thanks for your attention
