This is indeed the same symptoms I encountered in my case. More than that, I have an LSI 2008 adapter which is also being passed through in the same manner as the NIC, absolutely the same problem there too. Before doing the bisect I considered it a separate issue and planned to work on it later.

Patch fixed the issue for me. Did 4-5 reboots just to be sure, all working properly, no adapter resets. Just for the sake of experiment built a clean 4.7 kernel without the patch, issue still present there as expected.
