If TP fetches an SRQ buffer but ends up not using it before the connection is aborted, then it passes the index of that SRQ buffer to the host in ABORT_REQ_RSS or ABORT_RPL CPL message. But, if the srqidx field is zero in the received ABORT_RPL or ABORT_REQ_RSS CPL, then we need to read the tcb.rq_start field to see if it really did have an RQE cached. This works around a case where HW does not include the srqidx in the ABORT_RPL/ABORT_REQ_RSS CPL. The final value of rq_start is the one present in TCB with the TF_RX_PDU_OUT bit cleared. So, we need to read the TCB, examine the TF_RX_PDU_OUT (bit 49 of t_flags) in order to determine if there's a rx PDU feedback event pending.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
