getifaddrs() scalability

[Bruce M Simpson]

Just off the top of my head...
...has anyone run into problems with the scalability of this call?

One of the XORP users needs to create »1000 interfaces in Linux, and I'm 
wondering if any FreeBSD users need to create that amount of network 
interfaces.

As such the getifaddrs() call is likely to get slow in that scenario, as 
it uses a linked list.
