* net: more accurate checksumming in validate_xmit_skb()Davide Caratti2017-05-191-4/+7
| | | | | | | | | | | | | | | skb_csum_hwoffload_help() uses netdev features and skb->csum_not_inet to determine if skb needs software computation of Internet Checksum or crc32c (or nothing, if this computation can be done by the hardware). Use it in place of skb_checksum_help() in validate_xmit_skb() to avoid corruption of non-GSO SCTP packets having skb->ip_summed equal to CHECKSUM_PARTIAL. While at it, remove references to skb_csum_off_chk* functions, since they are not present anymore in Linux _ see commit cf53b1da73bd ("Revert "net: Add driver helper functions to determine checksum offloadability"").

* Documentation/networking: more accurate LCO explanationShmulik Ladkani2016-05-081-7/+7
| | | | | | | | | | | | In few places the term "ones-complement sum" was used but the actual meaning is "the complement of the ones-complement sum". Also, avoid enclosing long statements with underscore, to ease readability.
