Driver build fails on IEEE80211_CHAN_IGNORE

Software Linux
1

Hi @ajudge ,
I am building the latest morse_driver and still getting the below error:

morse_driver/dot11ah/s1g_channels.c:724:70: error: ‘IEEE80211_CHAN_IGNORE’ undeclared (first use in this function); did you mean ‘IEEE80211_CHAN_NO_HE’?
724 | __mors_s1g_map->s1g_channels[ch].ch.flags |= IEEE80211_CHAN_IGNORE;
| ^~~~~~~~~~~~~~~~~~~~~
| IEEE80211_CHAN_NO_HE

Can you please help me with this?

Thanks,

Arti

What’s the Linux kernel Version?

guess that you might need some patches.

Hi @BiaoWang ,
I am using 6.6.36 kernel.

We might need some kernel patches.

6.6.x.zip (17.9 KB)

Yes, you are missing the necessary patches.

An official source for these patches is:

See the last few commits; you should be able to apply them on your 6.6.36 kernel with minor/no alternation. If you’re not using git, you can use git format-patch to extract them. See:

for details (section 3).
