Subject: [PATCH net-next v3 2/2] gve: add XDP metadata support for DQ RDA
Date: Wed, 22 Jul 2026 15:16:34 -0700 [thread overview]
Message-ID: <20260722221634.186886-3-joshwash@google.com> (raw)
In-Reply-To: <20260722221634.186886-1-joshwash@google.com>
Commit 1b42e07af1ee ("gve: Add Rx HWTS metadata to AF_XDP ZC mode")
exposes support for the XDP RX timestamping metadata operation in the DQ
RDA mode. While the operation works on its own, the intent was to enable
XDP metadata support for the queue format as a whole along with it.
Currently bpf_xdp_adjust_meta fails because meta_valid is set to false.
This change updates xdp_buff preparation to set meta_valid to true, so
metadata can be fully used by XDP programs.
