I have a patch that resolves the first issue you're seeing (long ping times). I
have not had time to look at the second issue you've reported yet. Can you
please test out the patch below and let me know if it resolves your first issue?
For the patch, you can either open an issue on our SourceForge page where I can
upload the corrected driver for you or you can simply make the below code
changes to 1.9.5 of e1000e. If you would like me to deliver a patched driver
for you, please open a bug at SourceForge and let me know which version of the
driver you're using (plus whether it's the SourceForge or in-kernel driver).
Patch (for in e1000_watchdog_task)
