Write combining (WC) increases NIC performance by making better utilization of PCI bus, but cannot be use by all PMD. To get internal_addr memory need to be mapped. But as memory could not be mapped twice: with and without WC it should be skipped for WC. [1] To do not spoil other drivers that potentially could use internal_addr, parameter wc_activate adds possibility to skip it for those PMDs, that do not use it.
