Where is the documentation for the ifconfig output "flags" (not command 
line options)?

When my wireless goes down, I often see "OACTIVE".

In if.h I see:
define      IFF_OACTIVE     0x0400 /* transmission in progress */

Where are these documented? What man page should they be in?

I am tring to figure out why my wireless connection often stops working 
(when another system with some other operating system continues to work). 
I am running 3.99.21 on i386 with:

ral0 at uhub2 port 2

ral0: at uhub2 port 2 (addr 2) disconnected
ral0 detached

**Maybe that is when I unplugged it and plugged it back in to see if it 
would help.

It is a Linksys wireless G.

(No OACTIVE now but not working either ... a moment later and now it does 
work :)

What tools or techniques can be used to figure out why it sometimes works 
and sometimes does not?
