Subject: ipv4: Save nexthop address of LSRR/SSRR option to IPCB.
X-Git-Tag: v3.2-rc5~56^2~35
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac8a48106be49c422575ddc7531b776f8eb49610;p=pandora-kernel.git

ipv4: Save nexthop address of LSRR/SSRR option to IPCB.

We can not update iph->daddr in ip_options_rcv_srr(), It is too early.
When some exception ocurred later (eg. in ip_forward() when goto
sr_failed) we need the ip header be identical to the original one as
ICMP need it.

Add a field 'nexthop' in struct ip_options to save nexthop of LSRR
or SSRR option.
