- What: tcp_dma_copybreak sysctl
- Date: Removed in kernel v3.13
- Contact: Dan Williams <dan.j.williams@intel.com>
- Description:
- Formerly the lower limit, in bytes, of the size of socket reads
- that will be offloaded to a DMA copy engine. Removed due to
- coherency issues of the cpu potentially touching the buffers
- while dma is in flight.
