Subject: [patch 5/5] [PATCH] qeth: Clear SBALF15 in any case for output buffers.
Date: Wed, 20 May 2009 09:38:41 +0200 [thread overview]
Message-ID: <20090520073928.212451000@de.ibm.com> (raw)

[-- Attachment #1: 616-qeth-clear-SBALF15.diff --]
[-- Type: text/plain, Size: 957 bytes --]
From: Klaus-Dieter Wacket <kdwacker@de.ibm.com>
Function qeth_clear_output_buffer for HiperSockets may not clear
all 16 SBALEs, but only the used ones. The error flag in SBALF15
has to be cleared in any case.
