Instead of forcing all of the S/G entries to fit in one FMR, and falling back to indirect descriptors if that fails, allow the use of as many FMRs as needed to map the request. This lays the groundwork for allowing indirect descriptor tables that are larger than can fit in the command IU, but should marginally improve performance now by reducing the number of indirect descriptors needed. We increase the minimum page size for the FMR pool to 4K, as larger pages help increase the coverage of each FMR, and it is rare that the kernel would send down a request with scattered 512 byte fragments. This patch also move some of the target initialization code afte the parsing of options, to keep it together with the new code that needs to allocate memory based on the options given.
