[PATCH 0/2] target: Support MI_REPORT_TARGET_PGS extended header format

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi Hannes & Co,

This series adds support for MI_REPORT_TARGET_PGS extended header format
within ALUA target port group infrastructure, and adds 'implict_trans_secs'
tg_pt_gp attribute to set this value individually via configfs for each
/sys/kernel/config/target/core/$HBA/$DEV/alua/$ALUA_TG_PT_GP/ group.

This feature has been on my TODO list for a while, and now that Rob Evers
has posted the scsi_dh_alua.c changes to take advantage of this information
array side, it's now time to get this supported within target-core.

Note so far this has been tested with 'sg_raw a3 2a' on loopback LUNs, and
appears to be working as expected.  Please have a look and let me know if you
have any concerns.

Thanks!
