[PATCH 16/27] netfilter: move inline nf_ip6_ext_hdr() function to a more appropriate header.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jeremy Sowden <jeremy@xxxxxxxxxx>

There is an inline function in ip6_tables.h which is not specific to
ip6tables and is used elswhere in netfilter.  Move it into
netfilter_ipv6.h and update the callers.
