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. - -Signed-off-by: Gabor Juhos <j4g8y7@gmail.com> ---- - include/linux/skbuff.h | 3 +++ - 1 file changed, 3 insertions(+) - ---- a/include/linux/skbuff.h -+++ b/include/linux/skbuff.h -@@ -564,6 +564,9 @@ struct skb_shared_info { - unsigned int gso_type; - u32 tskey; - -+ unsigned int dsa_tag_proto; -+ unsigned char dsa_tag_data[8]; -+ - /* - * Warning : all fields before dataref are cleared in __alloc_skb() - */ |
