OSCL-LXR

0001 What:           tcp_dma_copybreak sysctl
0002 Date:           Removed in kernel v3.13
0003 Contact:        Dan Williams <dan.j.williams@intel.com>
0004 Description:
0005         Formerly the lower limit, in bytes, of the size of socket reads
0006         that will be offloaded to a DMA copy engine.  Removed due to
0007         coherency issues of the cpu potentially touching the buffers
0008         while dma is in flight.
