Add packet and byte counters for RX and TX paths.
$ ifconfig eth1
eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::5054:ff:fe12:3501 prefixlen 64 scopeid 0x20<link>
ether 52:54:00:12:35:01 txqueuelen 1000 (Ethernet)
RX packets 63 bytes 15813 (15.4 KiB)
RX errors 1 dropped 0 overruns 0 frame 0
TX packets 79 bytes 17991 (17.5 KiB)
TX errors 7 dropped 0 overruns 0 carrier 0 collisions 0
Rx / Tx errors tested by injecting faults in qemu's hardware model for Rocker.

- moved counter locations to avoid potential use after free per Florian's comment
