Subject: Re: [RFC v3 net-next 04/10] qed: Add slowpath L2 support
Hi Manish,
[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]
config: i386-allmodconfig (attached as .config)
reproduce:
git checkout 94302d8beecd786eb3a56ca1be467d3493c8943d
# save the attached .config to linux build tree
make ARCH=i386
