Replace kfree_skb() used in TLV encoded option header parsing with kfree_skb_reason(). Following functions are involved: ip6_parse_tlv() ipv6_hop_ra() ipv6_hop_ioam() ipv6_hop_jumbo() ipv6_hop_calipso() ipv6_dest_hao() Most skb drops during this process are regarded as 'InHdrErrors', as 'IPSTATS_MIB_INHDRERRORS' is used when ip6_parse_tlv() fails, which make we use 'SKB_DROP_REASON_IP_INHDR' correspondingly. However, 'IP_INHDR' is a relatively general reason. Therefore, we can use other reasons with higher priority in some cases. For example, 'SKB_DROP_REASON_UNHANDLED_PROTO' is used for unknown TLV options.

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 Restructured Text 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.
