Chandrakanth patil c432e16752 scsi: mpi3mr: Support for preallocation of SGL BSG data buffers part-1
The driver now supports SGLs for BSG data transfer. Upon loading, the
driver pre-allocates SGLs in chunks of 8k, results in a total of 256 * 8k,
equal to 2MB. These pre-allocated SGLs are reserved for handling BSG
commands and are deallocated during driver unload.
