[ Upstream commit d50729f1d60bca822ef6d9c1a5fb28d486bd7593 ] Some usb drivers try to set small skb->truesize and break core networking stacks. In this patch, I removed one of the skb->truesize override. I also replaced one skb_clone() by an allocation of a fresh and small skb, to get minimally sized skbs, like we did in commit1e2c611723("net: cdc_ncm: reduce skb truesize in rx path") and 4ce62d5b2f7a ("net: usb: ax88179_178a: stop lying about skb->truesize") v3: also fix a sparse error ( https://lore.kernel.org/oe-kbuild-all/202405091310.KvncIecx-lkp@intel.com/ ) v2: leave the skb_trim() game because smsc95xx_rx_csum_offload() needs the csum part. (Jakub) While we are it, use get_unaligned() in smsc95xx_rx_csum_offload().
