It looks like that could work, but it seems a lot easier to probe
network devices via normal manner, and then check if I can just
open and read /sys/class/net/[dev-name]/phy80211/name
I can do that easily from within a C/C++ program, where as
doing system calls and grabbing standard output is more of
a pain (and more overhead).
But, if you don't want to add my patch, it's not a big deal.
I don't really mind, it just didn't seem necessary. FWIW, readlink(2) is
also a system call that your C program could use, but if you want the
patch instead I guess that's fine.
I think it offers a bit of use at a small cost, but certainly
it's not a critical improvement.
If the maintainer picks it up, I'll happily use it..if not,
I can carry it in my own tree or use readdir or something.
Thanks,
Ben
