[PATCH] Net / pktgen: Fix freezing problem

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@xxxxxxx>
Subject: Net / pktgen: Fix freezing problem

Add missing try_to_freeze() to one of the pktgen_thread_worker() code
paths so that it doesn't block suspend/hibernation.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=15006
