Hi,

FYI, your patch has been queued to stable release 18.05.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.

Subject: [PATCH] net/i40e: fix shifts of 32-bit value

[ upstream commit bc98bf3a2d0301a17707bc04e95fc32746a397c4 ]

Cppcheck reports following error,
(error) Shifting 32-bit value by 36 bits is undefined behaviour

According to datasheet, there's PHY type and PHY type extension
in setting PHY config command, should exclude PHY type extension
when setting PHY type.
