Hi,
A different computer with the same type motherboard has the same
problem. A quad I350 (also wm(4)) works fine (with GENERIC netbsd-8
kernel).
Still wondering what queue drops are.
Grtnx,
Could you test the following diff?

Fix a bug that 8257[56] can't receive packet. For 82575 and 82576, the RX
descriptors must be initialized after the setting of RCTL.EN in
wm_set_filter(). This bug was added in if_wm.c rev. 1.515.
