| Subject: staging: r8712u: Fix regression in signal level after commit c6dc001 |
| |
| From: Larry Finger <Larry.Finger@lwfinger.net> |
| |
| commit da3e6ec2f443ac00aa623c5921e3521f5f38efe4 upstream. |
| |
| In commit c6dc001 "staging: r8712u: Merging Realtek's latest (v2.6.6). |
| Various fixes", the returned qual.qual member of the iw_statistics |
| struct was changed. For strong signals, this change made no difference; |
| however for medium and weak signals it results in a low signal that |
| shows considerable fluctuation, When using wicd for a medium-strength |
| AP, the value reported in the status line is reduced from 100% to 60% by |
| this bug. |
| |
| This problem is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42826. |
