Subject: [PATCH net-next v1] net: stmmac: Drop redundant skb_mark_for_recycle() for SKB frags
Date: Fri, 17 Jan 2025 14:28:05 +0800 [thread overview]
Message-ID: <20250117062805.192393-1-0x1207@gmail.com> (raw)
After commit df542f669307 ("net: stmmac: Switch to zero-copy in
non-XDP RX path"), SKBs are always marked for recycle, it is redundant
to mark SKBs more than once when new frags are appended.
