Subject: [PATCH v3 12/22] common/idpf: move related defines into enums
Date: Wed, 12 Jun 2024 03:52:47 +0000	[thread overview]
Message-ID: <20240612035257.2245824-13-soumyadeep.hore@intel.com> (raw)
In-Reply-To: <20240612035257.2245824-1-soumyadeep.hore@intel.com>

Changes all groups of related defines to enums. The names of
the enums are chosen to follow the common part of the naming
pattern as much as possible.

Replaced the common labels from the comments with the enum names.

While at it, modify header description based on upstream feedback.

Some variable names modified and comments updated in descriptive way.

+ * The total number of supported packet types is based on the descriptor type.
+ * For the flex descriptor, it is 1024 (10-bit ptype), and for the base
+ * descriptor, it is 256 (8-bit ptype). Send this message to the CP by
+ * populating the 'start_ptype_id' and the 'num_ptypes'. CP responds with the
+ * 'start_ptype_id', 'num_ptypes', and the array of ptype (virtchnl2_ptype) that
+ * are added at the end of the 'virtchnl2_get_ptype_info' message (Note: There
+ * is no specific field for the ptypes but are added at the end of the
+ * ptype info message. PF/VF is expected to extract the ptypes accordingly.
+ * Reason for doing this is because compiler doesn't allow nested flexible
+ * array fields).
+ *
+ * If all the ptypes don't fit into one mailbox buffer, CP splits the
+ * ptype info into multiple messages, where each message will have its own
+ * 'start_ptype_id', 'num_ptypes', and the ptype array itself. When CP is done
+ * updating all the ptype information extracted from the package (the number of
