Log message:
Fix i217 PHY initialization
Add a workaround for a hardware bug were receiving of packets would stop
until the battery of the laptop was removed. The problem could be
triggered if the LAN cable was plugged in after the PHY had already been
initialized.
The workaround is already present in FreeBSD (e1000_ich8lan.c:
e1000_lv_jumbo_workaround_ich8lan()) and Linux. The commit messages of
b20a7744 and da1e2046 in Linux have some more details.
Found and ported from FreeBSD by Valentin Dornauer.
Tested by many.
