Merge branch 'octeon_ep-transmit-cleanups-and-optimizations'
Shinas Rasheed says:
====================
Cleanup and optimizations to transmit code
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/
