Allocate mbufs for Rx path in bulk of at least 64 buffers
to improve performance. Allow recovery even without
a rx operation to support lack of buffers in pool.

Allocate mbufs for Rx path in bulk of at least 64 buffers
to improve performance. Allow recovery even without
a Rx operation to support lack of buffers in pool.
