I am using builtin NIC on my little Brix box and surprised to see lots
of byte count errors. Network seems a little sluggish at times.
Do use locally NFS mounted NAS for storing things like kernel trees.

this value is the same as rx_bytes above
Looking at the code it also looks like it's just a long (perhaps opposed
to just int counter) rx bytes count. No mention on errors.
No idea how much value it brings, but that's it not an error.
