The pages are classfied as either a zero page or a normal page. This
change uses Intel DSA to offload the zero page checking from CPU to
the DSA accelerator. The sen

During live migration, if the latency between sender and receiver
is high and bandwidth is also high (a long and fat pipe), using a bigger
packet size can help reduce migration total time. In addition, Intel
DSA offloading performs better with a large batch task. Providing an

A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found
by Linux kernel testing because it uses dual filter mode (MOD_AFM = 0)
and lea
