From 5f12b30bfc3ad667d7db2668014bbda968c1001c Mon Sep 17 00:00:00 2001 From: mav Date: Wed, 30 Dec 2015 11:51:35 +0000 Subject: MFC r292741: Make port logins asynchronous, following r292739 logic. This is even more important since it involves more network operations and more prone to delays and timeouts. --- sys/dev/isp/isp.c | 121 +++++++++++++++++++++++++----------------------------- 1 file changed, 55 insertions(+), 66 deletions(-) (limited to 'sys/dev') diff --git a/sys/dev/isp/isp.c b/sys/dev/isp/isp.c index b5385bc..95f0302 100644 --- a/sys/dev/isp/isp.c +++ b/sys/dev/isp/isp.c @@ -108,7 +108,7 @@ static void isp_fibre_init(ispsoftc_t *);
