Hi, all
During testing, below cmd is used to add a vlan dev.
vconfig add eth0 1000
Without the commit 88997e4208ae(I revert the patch in the
latest net-next)
ethtool -k eth0 | grep rx-checksumming
rx-checksumming: on
ethtool -k eth0.1000 | grep rx-checksumming
rx-checksumming: on [fixed]
ethtool -K eth0 rx off
ethtool -k eth0 | grep rx-checksumming
rx-checksumming: off
ethtool -k eth0.1000 | grep rx-checksumming
rx-checksumming: off [fixed]
-----------------------------------------
With the commit 88997e4208ae
ethtool -k eth0 | grep rx-checksumming
rx-checksumming: on
ethtool -k eth0.1000 | grep rx-checksumming
rx-checksumming: off [fixed]
ethtool -K eth0 rx off
ethtool -k eth0 | grep rx-checksumming
rx-checksumming: off
ethtool -k eth0.1000 | grep rx-checksumming
rx-checksumming: off [fixed]
So the vlan dev' rx-csum feature is not changed automatically
according to the lower dev' rx-csum feature after commit 88997e4208ae.
Is this a display issue? And Do we need to fix this issue?
MBR,
Yunsheng Lin
