adrianUnsubmitted Not Done Inline ActionsI don't THINK it was outdated; the logic was to start by a VHT80 lookup, and since the rest of the channel lookups only happen if c == NULL. I left that there so we could just keep adding new channel lookups above it. I forget when VHT160/80p80 came in. adrian: I don't THINK it was outdated; the logic was to start by a VHT80 lookup, and since the rest of… | |||||
