        TX errors 1679  dropped 0 overruns 0  carrier 1679  collisions 0

I'm seeing RX errors and dropped packets in addition to TX carrier errors on my IPsec \
VTI. I've played around with txqueuelen, which reduces the RX errors, but doesn't \
eliminate them. Has anyone else seen these or have an idea of configuration to \
change? I'm running libreswan 3.19 on CentOS 7.3.
