Hi Kalle, I have pushed two patches usingn 'git send-mail' and below patch is the first one; I could not see the patches in patchwork page(https://patchwork.kernel.org/project/linux-wireless/list/); Did you get this patch?

Current driver does not enable PME bit needed for WAKE# > assertion, causing host to remain in sleep even after WoWLAN conditions are > matched.
