This doesn't sound quite right, and if it's following the driver then there
might be a SW bug.
Can you send us the output of "ethtool -i "? A full dmesg would be good,
too, but attaching that to a bug on e1000.sourceforge.net would be the best
since this list strips attachments.

On a EXL710QDA2G1P5 card, after upgrading the NVM to 6.01 and driver to
2.1.26 on kernel 4.10, we get "Rx/Tx is disabled on this device because an
unsupported SFP+ module type was detected."
This is a unlocked card, and when reverting to the default kernel driver in
4.10, or using the 2.0.30
