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") and4ce62d5b2f("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().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
