While FMR will usually condense the requests into 8 SG entries, it is imperative that the target support external tables in case the FMR mapping fails or is not supported. We add a safety valve to allow targets without the needed support to reap the benefits of the large tables, but fail in a manner that lets the user know that the data didn't make it to the device. The user must add "allow_ext_sg=1" to the target parameters to indicate that the target has the needed support. If indirect_sg_entries is not specified in the modules options, then the sg_tablesize for the target will default to cmd_sg_entries unless overridden by the target options.
