Harmless ieee80211 errors in dmesg

[jvoisin]

I'm getting various errors from ieee80211 in my dmesg about broadcom hardware:

but the Wifi is working flawlessly, so this seems to be pretty harmless.

I have some of the same error message:

[ 1406.858831] ieee80211 phy0: brcmf_p2p_set_firmware: failed to update device address ret -52
[ 1406.859524] ieee80211 phy0: brcmf_p2p_create_p2pdev: set p2p_disc error
[ 1406.859528] ieee80211 phy0: brcmf_cfg80211_add_iface: add iface p2p-dev-wlp1s0f type 10 failed: err=-52

And they appear to be related to the wpa_supplicant service, as they pop up when I restarted it. This service is non-responsive, and is required to connect to P2P WiFi devices, so it's a bit niche but not harmless.

I discovered this trying to develop some P2P WiFi applications using wpa_supplicant which is the standard way for Linux P2P applications. Maybe an issue with the driver or with the Apple hardware?
