net/ice: add DCF hardware initialization Introduce the DCF (Device Config Function) feature in the ice PMD, it works as a standalone PMD which doesn't handle the packet Rx/Tx related things. Its hardware entity is the VF. Add the basic DCF hardware initialization, this is specified by devarg 'cap=dcf'.

net/ice: handle AdminQ command by DCF The DCF (Device Config Function) splits the AdminQ command into two parts: one is the descriptor of AdminQ command, the other is the buffer of AdminQ command (the descriptor has BUF flag set). When both of them are received by the PF, the PF will handle them as one command. And also, the filled descriptor and buffer of the response will be sent back to DCF one by one through the virtchnl from PF.

net/ice: handle PF initialization by DCF The DCF (Device Config Function) works at the user PF level, it can't access the real PF hardware directly. So it will pass through the PF's AdminQ command by the DCF's mailbox. And the DCF is mainly used to control the flow setting of other VFs, so it only needs to initialize some core functions related to the flow.
