Subject: [PATCH] net: skbuff: add size metadata to skb_shared_info for xdp
|
|
|
|
Introduce xdp_frags_size field in skb_shared_info data structure
|
|
to store xdp_buff/xdp_frame frame paged size (xdp_frags_size will
|
|
be used in xdp frags support). In order to not increase
|
|
skb_shared_info size we will use a hole due to skb_shared_info
|
|
alignment.
