iscsi/iser-target: Support multi-sequence sendtargets text response
In case sendtargets response is larger than initiator MRDSL, we send a partial sendtargets response (setting F=0, C=1, TTT!=0xffffffff), accept a consecutive empty text message and send the rest of the payload. In case we are done, we set F=1, C=0, TTT=0xffffffff. We do that by storing the sendtargets response bytes done under the session. This patch also makes iscsit_find_cmd_from_itt public for isert. (Re-add cmd->maxcmdsn_inc and clear in iscsit_build_text_rsp - nab) Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
