From: mav Date: Mon, 26 Oct 2015 18:14:15 +0000 (+0000) Subject: Reimplement enable and implement disable of virtual ports. X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=55afd42dc626901232c7eefae2066b592345871d;p=people%2Fliuw%2Ffreebsd.git Reimplement enable and implement disable of virtual ports. Now on 24xx and above chips it is really possible to simulate several virtual FC ports with single physical one. For example, it allows to configure several targets in ctl.conf, assign each of them to separate virtual port, and let user to control access to them with switch zoning. I still doubt that all problems are solved there, but at now it passes at least basic tests. --- diff --git a/sys/dev/isp/isp.c b/sys/dev/isp/isp.c index d78a9c36e38..72717b89a67 100644 --- a/sys/dev/isp/isp.c +++ b/sys/dev/isp/isp.c @@ -1275,7 +1275,12 @@ isp_reset(ispsoftc_t *isp, int do_load_defaults) */ if (IS_FC(isp) && isp->isp_nchan > 1) { if (!ISP_CAP_MULTI_ID(isp)) { - isp_prt(isp, ISP_LOGWARN, "non-MULTIID f/w loaded, only can enable 1 of %d channels", isp->isp_nchan);
