| Subject: mt76x0: run vco calibration for each channel configuration |
| |
| From: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> |
| |
| commit 473f0a763d2c7cd68a6dedf51e7d81e8f58f78ac upstream. |
| |
| According to vendor sdk, vco calibration has to be executed |
| for each channel configuration whereas mcu calibration has to be |
| performed during channel scanning. This patch fixes the mt76x0 |
| monitor mode issue since in that configuration vco calibration |
| was never executed |
| |
| Fixes: 10de7a8b4ab9 ("mt76x0: phy files") |
