Subject: [PATCH net-next v7 0/4] GVE Raw Addressing

Patch 1: Use u8 instead of bool for raw_addressing bit in gve_priv structure.
        Simplify pointer arithmetic: use (option + 1) in gve_get_next_option.
        Separate option parsing switch statement into individual function.
Patch 2: Use u8 instead of bool for raw_addressing bit in gve_gve_rx_data_queue structure.
        Correct typo in gve_desc.h comment (s/than/then/).
        Change gve_rx_data_slot from struct to union.
        Remove dma_mapping_error path change in gve_alloc_page - it should
        probably be a bug fix.
        Use & to obtain page address from data_ring->addr.
        Move declarations of local variables i and slots to if statement where they
        are used within gve_rx_unfill_pages.
        Simplify alloc_err path by using "while(i--)", eliminating need for extra "int j"
        variable in gve_prefill_rx_pages.
        Apply byteswap to constant in gve_rx_flip_buff.
        Remove gve_rx_raw_addressing as it does not do much more than gve_rx_add_frags.
        Remove stats update from elseif block, no need to optimize for infrequent case of
        work_done = 0.
Patch 3: Use u8 instead of bool for can_flip in gve_rx_slot_page_info.
        Move comment in gve_rx_flip_buff to earlier, more relevant patch.
        Fix comment wrap in gve_rx_can_flip_buffers.
        Use ternary statement for gve_rx_can_flip_buffers.
        Correct comment in gve_rx_qpl.
Patch 4: Use u8 instead of bool in gve_tx_ring structure.
        Get rid of unnecessary local variable "dma" in gve_dma_sync_for_device.

Catherine Sullivan (3):
  gve: Add support for raw addressing device option
  gve: Add support for raw addressing to the rx path
  gve: Add support for raw addressing in the tx path
