No,

I test with the version of the driver before patches and I have the same 
error.

I think error is in TX. (TX and RX equipments for the test have the same 
chip, I don't have other kind of chip available at the moment, that why 
I not sure)

If theses informations help :

When I transmit a paquet of ~ 4000 (for a mtu 4500),

When I reboot and PCIE-AER is compiled, I got this message :
