Question phy capabilities in 'iw'

[Ben Greear]

Here is the capabilities list from an mac80211_hwsim driver.

I am curious what information this is actually trying to convey.

For instance, why is AP in two different places, with different
values (2048 in first section, 8 in second) ?

	valid interface combinations:
		 * #{ IBSS } <= 1, #{ managed, AP, mesh point, P2P-client, P2P-GO } <= 2048,
		   total <= 2048, #channels <= 1
		 * #{ AP } <= 8,
		   total <= 8, #channels <= 1, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz, 80 MHz, 160 MHz }

Thanks,
Ben

That was probably just a copy-paste error -- check the commit that
introduced it, I'm guessing it came from ath10k or so.
