Hello, we had a similar problem with the e1000e driver on kernel 4.9.80 two years back. My college Wilfried Holzke fixed this issue with some changes in the file netdev-4.9-ethercat.c. You can find the description of the changes here: http://lists.etherlab.org/pipermail/etherlab-users/2018-September/018624.html
Hopefully this will fix your problem too.

This is my configuration: - Debian 10 i386 with a custom kernel 4.14.155-rt70a - IgH EtherCAT Master + Gavin's patchset 20190904 https://sourceforge.net/u/uecasm/etherlab-patches/ci/default/tree/ - I use both ec_r8169 and ec_e1000e drivers and it works very well. Notes: - I use i386 kernel because I need a single kernel that is compatible with all the computers I have. - I cannot use a standard Debian kernel because I need also VME bridge drivers. - The latest Linux kernel version in Gavin's patchset that supports both ec_r8169 and ec_e1000e is 4.14. Therefore I cannot use a more recent kernel for the moment. - For ec_e1000e, I use "Intel Corporation 82574L Gigabit" Regards, -- Sebastien BLANCHET On 8/26/20 11:33 AM, BUSSIERES Vincent wrote: > I add, the I’m not using generic driver but e1000e driver. > > Best regards > > *Vincent BUSSIERES* -- Etherlab-users mailing list Etherlab-users@etherlab.org http://lists.etherlab.org/cgi-bin/mailman/listinfo/etherlab-users -- Etherlab-users mailing list Etherlab-users@etherlab.org http://lists.etherlab.org/cgi-bin/mailman/listinfo/etherlab-users
