Subject: kernel log flooded with GET_CMD_NODE: cmd node not available

Hi,

I'm running kernel 4.1 (no code changes in mwifiex) on custom board
with mwrvl sd8787 sdio wifi card. Everything works fine but when I
start hostapd and connect to device from PC and open device webpage I
can see in log many of such messages (~100 same lines):
GET_CMD_NODE: cmd node not available
PREP_CMD: no free cmd node

I'm using fw: 14.66.35.p25

With 3.19 kernel I cannot see any of such messages. Any ideas? Thanks.

BR,

marek
