[dpdk-dev] [PATCH v5 08/38] bnxt: add completion ring support
Stephen Hurd

Wed Jun 15 00:55:41 CEST 2016
From: Ajit Khaparde <ajit.khaparde at broadcom.com>
Structures, macros, and functions for working with completion rings
in the driver.
Completion Ring is used by the Ethernet controller to provide the
status of transmitted & received packets, report errors, report
status changes to the host software, and inter-function forwarding
requests. In addition to the generic ring features, a completion ring
can have a statistics context that has statistics periodically DMAed
to host memory, along with a consumer index.
bnxt_handle_async_event() handles completions not related to a specific
transmit or receive ring such as link status changes which arrive on
the default completion ring.
Other physical or virtual functions on the same device may send an HWRM
command forward request. In this case, we will pass it through
unvalidated. In the future, we will be able to have the PF monitor and
control VF access to the HWRM interface if needed.
New HWRM Calls:
bnxt_hwrm_exec_fwd_resp:
Execute an encapsulated command and forward the response.
