Is this bug or feature ? From my point of view is somewhere lost any sum.
Or is it driver dependent? Kernel 2.6.23.1 (in 2.6.20.20 is the same behavior),
driver e1000. iproute2-ss070313; net-tools 1.60, ifconfig 1.42 (2001-04-13)
ifconfig gets its data from /proc/net/dev, which adds up rx_errors
and rx_missed.
