It seems to have been dropped in Trusty 3.12 but it's unclear why that happened.

They ware running Windows previously without problems. However under Ubuntu (22.04; 24.10) there is a problem with Intel i219-LM (13) NIC. Kernel module e1000e on load performs NVM checksum validation and fails. Tested sample suggests about 70% of laptops are affected. I modified e1000e module to bypass checksum and after that NIC works as it supposed to. I tried to correct NVM using ethtool and intel provided tool but it seems Dell locked writing to NVM on these laptops. I searched internet and this is not the first time this problem has occurred. There even used to be a patch adding module parameter to force checksum bypass (https://patchwork.ozlabs.org/project/ubuntu- kernel/patch/50c8f2b8.9020...@canonical.com/#470600). I wonder why ubuntu kernel is no longer shipped with this patch? Can you add this patch back or similar workaround?
