Subject: [PATCH] pcnet32: fix non-napi packet reception
Date: Wed, 17 Oct 2007 15:59:22 -0700 [thread overview]
Message-ID: <1192661962.474.10.camel@Linux.home> (raw)
Recent changes to the driver for the new napi API broke the reception of packets when in
non-napi mode. The initialization of napi.weight was removed for the non-napi case
leaving the value zero.
Tested NAPI and non-NAPI on x86_64.
