What: tcp_dma_copybreak sysctl

Date: Removed in kernel v3.13

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.
