Subject[PATCH 5.13 122/156] net: marvell: always set skb_shared_info in mvneta_swbm_add_rx_fragment
Date
From: Lorenzo Bianconi <lorenzo@kernel.org>

commit 6ff63a150b5556012589ae59efac1b5eeb7d32c3 upstream.

Always set skb_shared_info data structure in mvneta_swbm_add_rx_fragment
routine even if the fragment contains only the ethernet FCS.

Fixes: 039fbc47f9f1 ("net: mvneta: alloc skb_shared_info on the mvneta_rx_swbm stack")
