Hi Aleksandr,

I think that i40e_trace.h needs to be included in i40e_ethtool.c
as part of this patch.

 .../i40e_ethtool.c: In function ‘i40e_get_link_ksettings’:
 .../i40e_ethtool.c:1077:9: error: implicit declaration of function ‘i40e_trace’ [-Werror=implicit-function-declaration]
 1077 |         i40e_trace(ioctl_get_link_ksettings, pf, hw_link_info->link_info);
      |         ^~~~~~~~~~
