* scan_request->nr_ssids never 0 ? @ 2009-09-29 13:18 Holger Schurig 2009-09-29 14:04 ` Johannes Berg 0 siblings, 1 reply; 2+ messages in thread From: Holger Schurig @ 2009-09-29 13:18 UTC (permalink / raw) To: linux-wireless Even when I do an "iw xxx scan trigger", scan_request->nr_ssids is always 1 in my driver. Is this a bug or a feature? However, scan_request->ssids[0].ssid_len is 0. So to ask my firmware for an SSID scan, I need to do if (req->n_ssids && req->ssid[0].ssid_len) instead of simply if (req->n_ssids) -- http://www.holgerschurig.de ^ permalink raw reply [flat|nested] 2+ messages in thread
