> From: Prasad Kanneganti <[email protected]> > > Each Octeon output ring can DMA packets to host memory in two modes: info- > pointer mode and buffer-pointer-only mode. In info-pointer mode, Octeon > takes two buffer pointers for each packet and places the length of the > packet along with specified number of bytes from the beginning of the > packet into one buffer and the rest of the packet in a separate buffer. In > buffer-pointer-only mode, Octeon takes single buffer pointer and places the > length of the packet at the beginning of the buffer followed by the packet > data. > > This patch switches all Octeon output rings from info-pointer mode to > buffer-pointer-only mode. This results in fewer DMA setups and cache line > snoops. > > Signed-off-by: Prasad Kanneganti <[email protected]> > Signed-off-by: Derek Chickles <[email protected]> > Signed-off-by: Satanand Burla <[email protected]> > Signed-off-by: Felix Manlunas <[email protected]> Applied.
