Hi Jan,
i download the rtnet git head, but i have one compile error:
/home/matteot/rtnet-git/rtnet/drivers/e1000e/82571.c: In function
'e1000_get_hw_semaphore_82573':

make: *** [all-recursive] Error 1
Now i will open the code and i try to understand, but if you forgot
something in your last commit, please do now :)
I must download one specific Tag?
I don't understand very well your request, so i do the following:
Remove rtnet and reinstall the normal e1000e module.
i run the command lspci -nn and the lspci -vvk -d 8086:109a
bash# lspci -nn
