[Linaro-uefi] [PATCH v3 3/4] Drivers/Net/MarvellYukonDxe: Added multi-MAC and multi-controller support

Corrected the code for dual MAC controllers. The YUKON_DRIVER driver's structure includes a controller port number. The SNP interface functions passing a msk_if_softc object (corresponding to the controller interface) to the if_msk interface functions. Multi-controller and multi-MAC support: use a linked list to store the association between EFI controller handle and the interface data structure.
