-Subject: [PATCH] skbuff: add DSA specific data to struct skb_shared_info
-
-All of the already existing DSA tagging protocol drivers
-are storing the tagging data directly into the skb. In most
-cases that is the only way to send the required information
-to the underlying ethernet switch.
-
-However on certain platforms (like the Qualcomm IPQ40xx
-SoCs) the built-in ethernet switch is connected directly
-to an ethernet MAC, and the tagging information must be
-sent out-of-band which is done directly via the hardware
-TX descriptors of the ethernet MAC.
-
-In such cases, putting the information into the skb causes
-unneccesary overhead, because the ethernet driver must
-remove that before sending the ethernet frame towards to
-the hardware.
-
-This change adds two new DSA specific fields to struct
-skb_shared_info which makes it possible to send the
-tagging information via skb->shinfo. With this approach,
-the twofold modifications of the skb data can be avoided.
