Subject: iwlwifi: mvm: allow both d0i3 and d3 wowlan configuration modes
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=91742449479bd8666f9533efd9594a7d9f87bd0d;p=linux-beck.git

iwlwifi: mvm: allow both d0i3 and d3 wowlan configuration modes

d3 and d0i3 shouldn't be mutually exclusive. Set supported
wowlan triggers by looking for each of them, and check
on suspend/resume which flow should be used ("any" trigger
is supported by d0i3, and all the others by d3)
