The errors and frame counts indicate a network problem. You need to
check the setting on the switch and the network interface, and make
sure these are correct and compatible.

The same messages should appear in the syslog with timestamps.
Your problem look just like the problems I've seen when the switch and
the network interface had problems agreeing on the protocol settings.
Make sure both are set to autonegotiate, or lock both of them to the
setting you want.
You will have to check the documentation for your switch to find out
how to do it on the switch, and should be able to use ethtool or
mii-tool to fix the linux side.
