Re: [RTnet-users] Problem with e1000e driver

[Wojciech D. <woj...@gm...>]

I have found similar solution to the one presented at

https://www.mail-archive.com/rtnet-users@.../msg01326.html  

In my case, it was required to edit the rtnet script.
I have added 5 seconds of delay in submit_cfg() function, just after 
bringing rteth0 device up.

Does anyone know why the rt_e1000e driver can't handle this?
