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.
