The CTL frontend might have provided a buffer that is smaller than the FirstBurstLength and thus smaller than the amount of unsolicited data included in the request PDU. Treat these transfers as an empty transfer. Reported by: Jithesh Arakkan @ Chelsio Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D29940cgit |

A single union ctl_io can be reused across multiple transfers (in particular by the ramdisk backend). On a reuse, the reservation pointer would retain its value from the previous transfer tripping an assertion.

| a1c68734 | jhb | May 14, 2021, 7:17 p.m. | cxgbei: Add support for zero-copy iSCSI target transmission/read.
- Switch to allocating the cxgbei version of icl_pdu explicitly as a separate refcounted object allocated via malloc/free instead of storing it in the bhs mbuf prior to the bhs. - Support the icl_conn_pdu_queue_cb() method to set a callback on a PDU to be invoked when the PDU is freed. - For ICL_NOCOPY buffers, use an external mbuf to manage the storage for the buffer via m_extaddref(). Each external mbuf holds a reference on the associated PDU, so the callback is invoked once all of the external mbufs have been freed.

- Only allocate 16K jumbo mbufs if the region of data to be appended is sufficiently large, and use a loop. - Use m_getm2() to allocate a chain for data less than 16K, or if m_getjcl() fails. - Use ENOMEM as the return value instead of '1' if the hook fails due to a memory allocation error.

As a result, CPL_FW4_ACK now returns credits for these work requests. To support this, page pod work requests are now constructed in special mbufs similar to "raw" mbufs used for NIC TLS in plain TX queues. These special mbufs are stored in the ulp_pduq and dispatched in order with PDU work requests.
