[dpdk-dev] [PATCH 05/52] net/ice/base: consolidate implementation of MAC config set

[Qi Zhang <qi.z.zhang@intel.com>]

Consolidate implementation of ice_aq_set_mac_cfg for switch mode
and NIC mode. As per the specification, the driver needs to call
set_mac_cfg (opcode 0x0603) to be able to exercise jumbo frames.
