+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the drivers for all devices starting from our 40G product line
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * The Firmware copies the cookie fields when sending messages between the
+ * PF and VF, but uses all other fields internally. Due to this limitation,
+ * we must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the VSI indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value
+ * is of status_code type, defined in the shared type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of
+ * these opcodes. The VF driver must first validate the API version of the
+ * PF driver, then request a reset, then get resources, then configure
+ * queues and interrupts. After these operations are complete, the VF
+ * driver may start its queues, optionally add MAC and VLAN filters, and
+ * process traffic.

+ *
+ * For feature bits used *only* on the server-side:
+ *
+ * - In the first phase we indicate that a feature is DEPRECATED as of
+ * a particular release. This is the first major release X (say,
+ * jewel) that does not depend on its peers advertising the feature.
+ * That is, it safely assumes its peers all have the feature. We
+ * indicate this with the DEPRECATED macro. For example,
+ *
+ * DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL)
+ *
+ * because 10.2.z (jewel) did not care if its peers advertised this
+ * feature bit.
+ *
+ * - In the second phase we stop advertising the the bit and call it
+ * RETIRED. This can normally be done in the *next* major release
+ * following the one in which we marked the feature DEPRECATED. In
+ * the above example, for 12.0.z (luminous) we can say:
+ *
+ * DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS)
*
- * This was introduced by ceph.git commit
- * 9ea02b84104045c2ffd7e7f4e7af512953855ecd v0.58-657-g9ea02b8
- * and fixed by ceph.git commit
- * 4255b5c2fb54ae40c53284b3ab700fdfc7e61748 v0.65-263-g4255b5c
+ * - The bit can be reused in the first post-luminous release, 13.0.z
+ * (m).
+ *
+ * This ensures that no two versions who have different meanings for
+ * the bit ever speak to each other.

* __GFP_RECLAIM is shorthand to allow/forbid both direct and kswapd reclaim.
*
- * __GFP_REPEAT: Try hard to allocate the memory, but the allocation attempt
- * _might_ fail. This depends upon the particular VM implementation.
+ * The default allocator behavior depends on the request size. We have a concept
+ * of so called costly allocations (with order > PAGE_ALLOC_COSTLY_ORDER).
+ * !costly allocations are too essential to fail so they are implicitly
+ * non-failing by default (with some exceptions like OOM victims might fail so
+ * the caller still has to check for failures) while costly requests try to be
+ * not disruptive and back off even without invoking the OOM killer.
+ * The following three modifiers might be used to override some of these
+ * implicit rules
+ *
+ * __GFP_NORETRY: The VM implementation will try only very lightweight
+ * memory direct reclaim to get some memory under memory pressure (thus
+ * it can sleep). It will avoid disruptive actions like OOM killer. The
+ * caller must handle the failure which is quite likely to happen under
+ * heavy memory pressure. The flag is suitable when failure can easily be
+ * handled at small cost, such as reduced throughput
+ *
+ * __GFP_RETRY_MAYFAIL: The VM implementation will retry memory reclaim
+ * procedures that have previously failed if there is some indication
+ * that progress has been made else where. It can wait for other
+ * tasks to attempt high level approaches to freeing memory such as
+ * compaction (which removes fragmentation) and page-out.
+ * There is still a definite limit to the number of retries, but it is
+ * a larger limit than with __GFP_NORETRY.
+ * Allocations with this flag may fail, but only when there is
+ * genuinely little unused memory. While these allocations do not
+ * directly trigger the OOM killer, their failure indicates that
+ * the system is likely to need to use the OOM killer soon. The
+ * caller must handle failure, but can reasonably do so by failing
+ * a higher-level request, or completing it only in a much less
+ * efficient manner.
+ * If the allocation does fail, and the caller is in a position to
+ * free some non-essential memory, doing so could benefit the system
+ * as a whole.
*
* __GFP_NOFAIL: The VM implementation _must_ retry infinitely: the caller
- * cannot handle allocation failures. New users should be evaluated carefully
- * (and the flag should be used only when there is no reasonable failure
- * policy) but it is definitely preferable to use the flag rather than
- * opencode endless loop around allocator.
- *
- * __GFP_NORETRY: The VM implementation must not retry indefinitely and will
- * return NULL when direct reclaim and memory compaction have failed to allow
- * the allocation to succeed. The OOM killer is not called with the current
- * implementation.
+ * cannot handle allocation failures. The allocation could block
+ * indefinitely but will never return with failure. Testing for
+ * failure is pointless.
+ * New users should be evaluated carefully (and the flag should be
+ * used only when there is no reasonable failure policy) but it is
+ * definitely preferable to use the flag rather than opencode endless
+ * loop around allocator.
+ * Using this flag for costly allocations is _highly_ discouraged.

+ * you feel the need to use it, please check to see if there is
+ * a better way to get your job done.
+ *
+ * The ordering guarantees provided by spin_unlock_wait() are:
+ *
+ * 1. All accesses preceding the spin_unlock_wait() happen before
+ * any accesses in later critical sections for this same lock.
+ * 2. All accesses following the spin_unlock_wait() happen after
