This fixes bug that could cause WARNING on every add_key/del_key call. It also replaces WARNING with a simple message. They may still occur e.g. on station going out of range and A-MPDU stall in the firmware. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] brcmfmac: use correct skb freeing helper when deleting
|
|
flowring

Flowrings contain skbs waiting for transmission that were passed to us
|
|
by netif. It means we checked every one of them looking for 802.1x
|
|
Ethernet type. When deleting flowring we have to use freeing function
|
|
that will check for 802.1x type as well.
|
|
|
|
Freeing skbs without a proper check was leading to counter not being
|
|
properly decreased. This was triggering a WARNING every time
|
|
brcmf_netdev_wait_pend8021x was called.
