Pad small packets to ETH_ZLEN before transmit, cleanup dma sync calls,
add xmit_more functionality and then further remove atomic
variable usage in the prior.

Changes:
V3:
  - Stop returning NETDEV_TX_BUSY when ring is full in xmit_patch.
    Change to inspect early if next packet can fit in ring instead of
    current packet, and stop queue if not.
  - Add smp_mb between stopping tx queue and checking if tx queue has
    free entries again, in queue full check function to let reflect
    IQ process completions that might have happened on other cpus.
  - Update small packet padding patch changelog to give more info.
V2: https://lore.kernel.org/all/20231024145119.2366588-1-srasheed@marvell.com/
  - Added patch for padding small packets to ETH_ZLEN, part of
    optimization patches for transmit code missed out in V1
  - Updated changelog to provide more details for dma_sync remove patch
  - Updated changelog to use imperative tone in add xmit_more patch
V1: https://lore.kernel.org/all/20231023114449.2362147-1-srasheed@marvell.com/

Pad small packets to ETH_ZLEN before transmit, as hardware
cannot pad and requires software padding to ensure
minimum ethernet frame length.

Cleanup dma sync calls for scatter gather
mappings, since they are coherent allocations
and do not need explicit sync to be called.

Replace atomic variable "instr_pending" which represents number of
posted tx instructions pending completion, with host_write_idx and
flush_index variables in the xmit and completion processing respectively.

## Form letter - net-next-closed

The merge window for v6.7 has begun and we have already posted our pull
request. Therefore net-next is closed for new drivers, features, code
refactoring and optimizations. We are currently accepting bug fixes only.

Please repost when net-next reopens after Nov 12th.

RFC patches sent for review only are obviously welcome at any time.
