Hi Atul,

Thank you for the patch! Yet we hit a small issue.
[auto build test ERROR on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Atul-Gupta/cxgb4-Add-support-for-Inline-IPSec-Tx/20171029-060344
config: x86_64-kexec (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All errors (new ones prefixed by >>):
