Subject: [PATCH] xl: fix strtok() call in vif2 parsing
Date: Fri, 20 Aug 2010 13:58:36 +0200	[thread overview]
Message-ID: <4C6E6DEC.5030601@amd.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 356 bytes --]

Hi,

according to the manpage subsequent calls to strtok() must use
NULL in the string parameter to keep the iteration going.
Fix fixes a hang when parsing the vif2 parameter.

Regards,
Andre.
