Interestingly enough, a similar bug probably once existed in sysinstall.
In /usr/src/release/sysinstall/devices.c, routine deviceGetAll(), there
is a loop through these structures which also erroneously uses ++ to
increment the struct ifreq* pointer. At the end of the loop, after the
label loopend:, there is a line of code that fixes the pointer, together
with a comment "I'm not sure why this is here - it's inherited".
