Unfortunatelly I've not followed the last two or three weeks commits (new
semester started and so now I rarely have time to fix my personal bridge)
but tonight I synched my tree and immediately noticed a rather nasty bug!

[Using libbb/interface.c:1.24]
# grep eth0 /proc/net/dev | xargs
eth0:311708397 237346 1670 0 1789 1670 0 0 22580308 120297 0 0 0 102 0 0

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:20:AF:7C:EA:B7
          inet addr:10.0.0.1  Bcast:10.0.0.127  Mask:255.255.255.128

All values `ifconfig' is showing are `zeroed' -- I quickly looked at the
last commits I missed and noticed that there were a commit relating to
ifconfig, libbb/interface.c:1.23->1.24 (PatchSet 4338).

I've reversed the patch and now everything is working again.  I compared
the get_name's return values from the 1.23 and 1.24 and quickly noticed
that the new revision is leaving `p' right on the sep while the rev 1.23
was leaving it right on the starting of the values...

1-line, 1/3-minute patch attached  :-)
