Compilation error on ARM with IEEE80211_CHAN_IGNORE

[gavoco]

Example error (there's a few)
morse_driver/mac.c:3373:55: error: ‘IEEE80211_CHAN_IGNORE’ undeclared (first use in this function); did you mean ‘IEEE80211_CHAN_NO_HE’? 3373 | ((conf->chandef.chan->flags & IEEE80211_CHAN_IGNORE) == 0)); | ^~~~~~~~~~~~~~~~~~~~~

removing the ifdef around the declaration which limits this declaration to X86_64 in mac.h fixes the issue

'Fixing' it this way will cause you other issues in terms of channel selection as it will incorrectly disable some channels (and apologies for the x86_64 hack).

The reason it's like this is that we expect you to apply a set of kernel patches, one of which adds IEEE80211_CHAN_IGNORE. See https://github.com/MorseMicro/linux
