This may cause us to call the id generation multiple times. With 32bit ID, you certainly can replace fragid=0 by fragid=0x80000000 and nobody will notice. I certainly vote for not adding an extra bit in skb or skb_shared_info, considering we already consume 32bits for this thing. fragid are best effort, otherwise they would have 128bits. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
