I now tried net-next 6d0722a2cec2c23db3b0855ff8bb433175a16b44, it works fine,
with ethtool -K tx/rx on and off.
I used the same .config as with (make oldconfig).
I retested, it's still okay.

And unfortunately did not work very well after rebooting,
I had to waste a lot of time playing with -K tx off rx off, -K tx on rx on, etc.
Before it started working, eth0 had interrupts occurring only on CPU0.
CPU1 started getting some usage only after dhclient started working..
Probably irrelevant, but I am running out of ideas.
I have tried e1000e param IntMode 0, 1, 2, no luck.
