From c558a72db604b431e22dcdb960bbde42f09d53a7 Mon Sep 17 00:00:00 2001 From: mav Date: Fri, 13 Nov 2015 19:59:22 +0000 Subject: [PATCH] MFC r290054: Reimplement next port handle generation. For some reason port handles should be allocated from HBA-global space, while old code was not very specific, mixing per-HBA and per-VP logic. git-svn-id: svn://svn.freebsd.org/base/stable/10@290800 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f --- sys/dev/isp/isp.c | 100 +++++++++++++++++++------------------------ sys/dev/isp/ispvar.h | 3 -- 2 files changed, 43 insertions(+), 60 deletions(-) diff --git a/sys/dev/isp/isp.c b/sys/dev/isp/isp.c index 72717b89a..d23f6780c 100644 --- a/sys/dev/isp/isp.c +++ b/sys/dev/isp/isp.c @@ -130,7 +130,7 @@ static int isp_scan_fabric(ispsoftc_t *, int);
