Subject: [PATCH 26/50] net: dsa: mv88e6xxx: collapse disabled state into
|
|
blocking
|
|
|
|
This patch changes the behavior of switchcore ports wrt. the port state.
|
|
Instead of disabling the port, the driver now treats the disabled state
|
|
the same as the blocking and listening state.
|
|
|
|
On this particular type of device the disabled state means no traffic is
|
|
passed in or out. This interferes with protocols that perform any type
|
|
of link qualification. E.g., an LACP link aggregate (bond) used as a
|
|
bridge port with member ports from an mv88e6xxx switch core. Without
|
|
this patch, the bond is set to 'state disabled'. which is offloaded to
|
|
each member port, preventing LACPDUs from passing through to qualify the
|
|
link and become active.
