β¨ libeth_xdp_buff_stats_frags β¨
okay so real talk, bestie β welcome to the libeth_xdp_buff_stats_frags(9) page from the Kernel API Manual π
this one's a tiny little internal helper and she is very much behind-the-scenes, so let's get into it π«Ά
πΈ NAME πΈ
libeth_xdp_buff_stats_frags β bestie, this is the one that updates your onstack RQ stats with all that XDP frags info β¨
π SYNOPSIS π
void libeth_xdp_buff_stats_frags (struct libeth_rq_napi_stats *ss ,
const struct libeth_xdp_buff *xdp );
like, that's literally the whole signature, no cap π
π¦ ARGUMENTS π¦
ssβ the onstack stats you're updating, she's the main character here πxdpβ the buffer that's getting accounted for, gotta count her too π§
π DESCRIPTION π
okay so listen β this is an internal helper used by __libeth_xdp_run_pass, and the vibe check is clear: do not call it directly π it's giving "backstage crew, not the opening act."
what she actually does? she takes the buffer's frags count and total len and adds them to the onstack stats. that's it. that's the whole job. iconic, honestly β
