From cf53b069f52ae3f83dec1acd339e3c3a2e979478 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Thu, 20 Aug 2009 11:06:04 -0700 Subject: [SCSI] qla2xxx: Generalize srb structure usage. Lay groundwork for adding alternative asynchronous operations by generalize and extending the SRB structure. This allows for follow-on patches to add support for: - Asynchronous logins. - ELS/CT passthru requests. - Loopback requests. - Non-blocking mailbox commands (ABTS, Task Management, etc).
