From 43ef058010c79a967195539bbcdeee8c5b24219d Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Thu, 17 Jan 2008 09:02:08 -0800 Subject: [PATCH] [SCSI] qla2xxx: Retrieve additional HBA port statistics from recent ISPs. HBAs supporting these additional counters include ISP24xx and ISP25xx type boards.
