1 Release Date : Thur. Oct 29, 2009 09:12:45 PST 2009 -
(emaild-id:megaraidlinux@lsi.com)
Bo Yang
2 Current Version : 00.00.04.17.1-rc1
3 Older Version : 00.00.04.12
1. Add the pad_0 in mfi frame structure to 0 to fix the
context value larger than 32bit value issue.
2. Add the logic drive list to the driver. Driver will
keep the logic drive list internal after driver load.
3. driver fixed the device update issue after get the AEN
PD delete/ADD, LD add/delete from FW.
