Subject: [PATCH] [FEAT LS1502] lsdasd/tunedasd: Add channel path aware erp
From: Stefan Haberland <sth@linux.vnet.ibm.com>

Summary:     lsdasd/tunedasd: Add channel path aware erp
Description: Add tools support for channel path aware error recovery.
             lsdasd shows the newly added IFCC path mask and HPF availability.
             tunedasd gets an option to reset channel paths for a device.
