Requirement:
In skb recycler, if recyler module allocates the buffers
already used by DS module to DS, then memzero, shinfo
reset can be avoided, since the DS packets were not
processed by SW (host).
Hence, we will achieve good KPI with less CPU
utilization.
Fix:
Implemented an new qdf wrapper API qdf_nbuf_alloc_ppe_ds
in wifi driver, which in turn invokes
__netdev_alloc_skb_no_skb_reset API to linux module.
With the use of new netdev_alloc API shinfo reset
will be avoided for DS used buffers alone.
