[dpdk-dev] [PATCH 13/69] net/i40e/base: add check for MAC type

[Xiaolong Ye]

Some features were introduced in different FW API version on XL710 and X722
MACs. Others are available only on specific MAC type. Make sure that they
are properly assigned. Also fix the style issues reported by current
check-patch.
