Hello Johannes,

While poking around in things, I noticed that the
he_capa debugfs is not showing the least-common-denominator, but rather
more specifically the peer's capabilities.

This could be bugs in how I'm using this, but thought I'd ask to
see if this was on purpose or not.

Code in question looks like this.  That sta->sta.he_cap is
from the peer as far as I can tell.  The local one is obtained
from the radio/driver (and then modified a bit in some hackings
I am doing).

static ssize_t sta_he_capa_read(struct file *file, char __user *userbuf,
				size_t count, loff_t *ppos)
{
	char *buf, *p;
	size_t buf_sz = PAGE_SIZE;
	struct sta_info *sta = file->private_data;
	struct ieee80211_sta_he_cap *hec = &sta->sta.he_cap;
	struct ieee80211_he_mcs_nss_supp *nss = &hec->he_mcs_nss_supp;

Thanks,
Ben
