Subject: [PATCH 2.6.12-rc3] pcnet32: fix resource leak with loopback test (with Signed-off-by)
Date: Fri, 29 Apr 2005 14:51:17 -0700 [thread overview]
Message-ID: <20050429215117.GA1082@us.ibm.com> (raw)
When running the loopback test, resources are not properly released on
completion. This patch frees all transmit resources after running the
loopback test. Tested on ia32 and ppc64 hardware.
