| Subject: cfg80211: make RATE_INFO_BW_20 the default |
| |
| From: Johannes Berg <johannes.berg@intel.com> |
| |
| |
| [ Upstream commit 842be75c77cb72ee546a2b19da9c285fb3ded660 ] |
| |
| Due to the way I did the RX bitrate conversions in mac80211 with |
| spatch, going setting flags to setting the value, many drivers now |
| don't set the bandwidth value for 20 MHz, since with the flags it |
| wasn't necessary to (there was no 20 MHz flag, only the others.) |
| |
| Rather than go through and try to fix up all the drivers, instead |
| renumber the enum so that 20 MHz, which is the typical bandwidth, |
| actually has the value 0, making those drivers all work again. |
| |
| If VHT was hit used with a driver not reporting it, e.g. iwlmvm, |
| this manifested in hitting the bandwidth warning in |
| cfg80211_calculate_bitrate_vht(). |
