How to allocated SKB in specific limited area only?
 

My Network Device has "same/similar" Network-Driver in Kernel space and in User Space.
In User Space HW-registers, buffers and shared memory
are mapped over uio (limited mmap areas).

Is it possible / How to
allocate SKB in shared area only but not "anywhere" in huge RAM?

I have looked similar configuration
"Recycle SKB from Static SKB-pool"
but didn't found anything...
