MikroTik 760iGS: Incorrect network counters

Installing and Using OpenWrt
1

Device MikroTik RouterBOARD 760iGS

Running speed test from the lan side to https://speedtest.net and looking at the network counters, the only interface showing any sign of activity is eth0. It also seems both Rx/Tx show combined in/out values.

Hardware acceleration on.

Hardware acceleration skips most of normal network stack. For example both bridges will not see anything that is offloaded. You may get real transfer of physical ports via ethtool -s
