APAR Error Description / Circumvention

-----------------------------------------------
Determining root cause of bridging errors is very difficult.
One especially difficult case is detecting conflicts between
multiple bridging-capable (or "trunk") adapters in the same
hypervisor virtual Ethernet VLAN.

CORRECTION FOR APAR MA44379 :
-----------------------------
Licensed internal code has been changed to detect cases in which
a bridging virtual Ethernet line description has had the
bridging ability taken away by some other virtual Ethernet
adapter. Product Activity Log (PAL) entries will be written, and
the trunk ability will be restored at the next vary-on of the
line description. A PAL entry with reference code B025A001,
secondary code 00000001, and component VIO indicates a line
description has restored its bridging ability. A PAL entry with
reference code B025A001, secondary code 00000002, and component
VIO indicates a line description has had its bridging ability
taken away by another virtual Ethernet adapter.

CIRCUMVENTION FOR APAR MA44379 :

None.
