net: usb: smsc95xx: stop lying about skb->truesize
[ 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 commit 1e2c61172342 ("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().
Fixes: 2f7ca802bdae ("net: Add SMSC LAN9500 USB2.0 10/100 ethernet adapter driver")
