Subject: [xdp-hints] Questions about XDP hints
Date: Sat, 12 Oct 2024 09:12:21	[thread overview]
Message-ID: <90c1c6b53a654cf197eb412917fad31a@huawei.com> (raw)

Hi all:
	There has been some discussions about adding checksum hint in AF_XDP such as this thread[1]. Now, we also plan to add checksum hint. My questions are:
	1. In this msg[2], is it appropriate if xdp_csum_status only includes 4 enums/macros(CHECKSUM_NONE...CHECKSUM_PARTIAL in skbuff.h)? Thus it becomes more generic. Also, in this msg[3] we can simply pass skb->ip_summed to csum_status in veth_xdp_rx_csum().
	2. What should be taken care of if I want to add a new hint? IOW, what is acceptable to add a new hint?

Thanks!
