Test with kernel 4.4.127-4.g662314f-default

Dear Benjamin, thanks a lot! Seems to work.

Since I'd like to understand a bit more, may I ask some questions?

Why does it sometimes need a second attempt to get a response from
"er32(TSYNCRXCTL) & E1000_TSYNCRXCTL_SYSCFI" in netdev.c?
Your test would try up to ten times but up to now I only observed failed first
attempts.

Does this problem only affect kernel 4.4 and is not happening in newer kernels?
The code in file netdev.c, function e1000e_get_base_timinca looks unchanged for
me when accessing the adapter variant "spt".

Thanks again, Achim
