From f92de9d110429e39929a49240d823251c2fe903e Mon Sep 17 00:00:00 2001 From: Tyler Erickson Date: Thu, 2 Jun 2022 16:51:13 -0600 Subject: scsi: sd: Fix interpretation of VPD B9h length Fixing the interpretation of the length of the B9h VPD page (Concurrent Positioning Ranges). Adding 4 is necessary as the first 4 bytes of the page is the header with page number and length information. Adding 3 was likely a misinterpretation of the SBC-5 specification which sets all offsets starting at zero.

The target then sends a LOGO to the fabric DID. lpfc is currently treating the LOGO from the fabric DID as a link down and cleans up all the ndlps.

Nevertheless, gcc complains because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus doesn't fit into those 20 bytes. This patch simply allocates all 32 bytes (instead of 20) and thus avoids the warning. There is no functional change introduced by this patch. While touching the code I cleaned up to calculation of max_wideport_qd, max_narrowport_qd and max_sata_qd to make it easier readable.
