Subject: Re: [PATCH net-next] qed*: Utilize Firmware 8.15.3.0
Hi Yuval,
[auto build test WARNING on net-next/master]
url: https://github.com/0day-ci/linux/commits/Yuval-Mintz/qed-Utilize-Firmware-8-15-3-0/20170310-154337

reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=xtensa
