- The default initialization of hdr_max is the minimum -
sizeof(struct iscsi_cmd) - Once this patch goes into iser the default
initialization at libiscsi can be removed.
- This is not yet full support for AHSs at iser end. But it should be easy.
Just allocate more space at iser_desc right after iscsi_hdr. Than
at transmission time use ctask->hdr_len to retrieve the total
size of all iscsi pdu headers. See previous patch at iscsi_tcp.[ch]
