[PATCH net] net: ethernet: ti: am65-cpsw-nuss: Fix skb size by accounting for skb_shared_info
From: Chintan Vankar
Date: Wed Jun 25 2025 - 07:35:47 EST
While transitioning from netdev_alloc_ip_align to build_skb, memory for
skb_shared_info was not allocated. Fix this by including
sizeof(skb_shared_info) in the packet length during allocation.
Fixes: 8acacc40f733 ("net: ethernet: ti: am65-cpsw: Add minimal XDP support")
