The first thing to look for is are packets showing up (and being transmitted)
by doing
ethtool -S eth0
Since in this driver stats come out of the PHY, it is possible for the PHY
to be receiving packets but have the bus interface wedged.
It also will tell you if you have pause frames going back and forth.
You might have a bad switch that doesn't do flow-control properly.
Next you can turn on debug with:
ethtool -s eth0 msglvl 0xfff
and see if packets are being received and transmitted.
In your case, it looks like the driver is receiving and transmitting fine;
so it probably is in the upper layers. So look into higher level statistics
like: netstat (or ip and ss).
Other possiblities:
* turn off TSO
ethtool -K eth0 tso off
* turn off Tx checksum
ethtool -K eth0 tx off
* turn off Rx checksum
ethtool -K eth0 rx off
If you get things really wedged and want to dig into the driver and
look at all the registers. But it really requires lots of time to decode...
ethtool -d eth0 raw on >/tmp/eth0.dump
hexdump /tmp/eth0.dump
