        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.
