Subject: Manage race condition when deleting interface
X-Git-Tag: 4.0.0~55
X-Git-Url: https://git.opendaylight.org/gerrit/gitweb?p=transportpce.git;a=commitdiff_plain;h=63b895ed9235fbcb7a801941470345f39d2238b2

Manage race condition when deleting interface

Since rendering tasks are parallelized, an exception may occur if the
interface to delete has just been deleted by another task. Delete action
on the device datastore needs to be in a monolithic block.
