Commit Message

Ganapati Kundapura April 18, 2023, 9:16 a.m. UTC 
  In case of CRYPTO_ADAPTER_OPS_BUFFER_SZ is modified,
eca_circular_buffer_space_for_batch() also needs to be updated
to check maximum number of crypto ops can be accommodated in
circular buffer when CPM becomes busy.

Defined MAX_OPS_IN_BUFFER which contains size for batch of dequeued events
and redefined CRYPTO_ADAPTER_OPS_BUFFER_SZ in terms of MAX_OPS_IN_BUFFER.

This patch makes eca_circular_buffer_space_for_batch() independent of
circular buffer changes.
