From: "Chen Jing D(Mark)" <jing.d.chen@intel.com>

v4:
 - Clear HW/SW ring content after allocating mbuf failed.

v3:
 - Add a blank line after variable definition.
 - Do floor alignment for passing in argument nb_pkts to avoid memory overwritten.
 - Only scan max of 32 desc in scatter Rx function to avoid memory overwritten.

v2:
 - Fix a typo issue.
 - Fix an improper prefetch in vector RX function, in which prefetches
   un-initialized mbuf.
 - Remove limitation on number of desc pointer in vector RX function.
 - Re-organize some comments.
 - Add a new patch to fix a crash issue in vector RX func.
 - Add a new patch to update release notes.

v1:
This patch set includes Vector Rx/Tx functions to receive/transmit packets
for fm10k devices. It also contains logic to do sanity check for proper
RX/TX function selections.

Chen Jing D(Mark) (16):
  fm10k: add new vPMD file
  fm10k: add vPMD pre-condition check for each RX queue
  fm10k: Add a new func to initialize all parameters
  fm10k: add func to re-allocate mbuf for RX ring
  fm10k: add 2 functions to parse pkt_type and offload flag
  fm10k: add Vector RX function
  fm10k: add func to do Vector RX condition check
  fm10k: add Vector RX scatter function
  fm10k: add function to decide best RX function
  fm10k: add func to release mbuf in case Vector RX applied
  fm10k: add Vector TX function
  fm10k: use func pointer to reset TX queue and mbuf release
  fm10k: introduce 2 funcs to reset TX queue and mbuf release
  fm10k: Add function to decide best TX func
  fm10k: fix a crash issue in vector RX func

Sorry, there are some checkpatch warnings and a compilation error:

SPACING: No space is necessary after a cast
SPACING: spaces preferred around that '+'
LINE_CONTINUATIONS: Avoid unnecessary line continuations

And more important, with clang:

fm10k_rxtx_vec.c:69:1: error: unused function 'fm10k_rxq_rearm'
  

Hi, Thomas,

Best Regards,
Mark

Thanks for the comments. I'll fix it.
