Oh, thanks for the fix.  I think I used e1000 so it would match a kernel
file when I entered the bug report.  You are right that e1000e is what
the kernel reports on the error lines:

	[ 1351.850362] NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0	timed out
	                                      ^^^^^^

Current settings:

	$ ethtool -a eth0
	Pause parameters for eth0:
	Autonegotiate:  on
	RX:             on
	TX:             on

I then ran:

	$ ethtool -A eth0 rx off tx off

	$ ethtool -a eth0
	Pause parameters for eth0:
	Autonegotiate:  on
	RX:             on
	TX:             on

It seems nothing changed.

Wow, that seems more risky than just buying a dual-port PCI-E ethernet
card and using that.  FYI, this server is from 2012 so I am worried such
an upgrade would break things more than fix them.

If there is no known fix I think that will be my next try, in a long
list of many attempts to fix this.
