Subject: [PATCH 1/9] lpfc 8.1.3 : Derive supported speeds from LMT field in the READ_CONFIG
Date: Wed, 22 Feb 2006 12:33:14 -0500 [thread overview]
Message-ID: <43FCA05A.803@emulex.com> (raw)
Derive supported speeds from LMT field in the READ_CONFIG
Driver was keying off internal cores. Use what the firmware reports instead.
