#nicinfo wm0

shows an increase in the number of errors

Squelch Test errors .......

Which leads to a failure in the qnet and Tcpip protocols.

Driver devnp-qnet.so vid = 0x8086, did = 0x15b3

NAME = devnp-e1000.so
DESCRIPTION = Driver for Intel 82544 Gigabit Ethernet controllers
DATE = 2015/11 / 30-12: 50: 20-EST
STATE = stable
HOST = gusbuild8
USER = builder
VERSION = 1344
TAGID = PSP_networking_br650_be650SP1

What could be the causes of failures, what could be the recommendations?

Thanks
