than the chanctx\n\nFrames injected on a monitor interface can carry a radiotap\nfield requesting a bandwidth, which mac80211 passes down to\nthe driver regardless of the the actual operational bandwidth.\n\nIf the bandwidth requested is too wide, that triggers a warning\nin hwsim:\n\n  WARN_ON(hwsim_get_chanwidth(bw) > hwsim_get_chanwidth(confbw))\n\nDrop such frames entirely instead since
