From: Gavin Shan <redacted>
The length of GVI (GetVersionInfo) response packet should be 40 instead
of 36. This issue was found from /sys/kernel/debug/ncsi/eth0/stats.
# ethtool --ncsi eth0 swstats
:
RESPONSE OK TIMEOUT ERROR
=======================================
GVI 0 0 2
With this applied, no error reported on GVI response packets:
# ethtool --ncsi eth0 swstats
:
RESPONSE OK TIMEOUT ERROR
=======================================
GVI 2 0 0
