Subject: ipv6cp: Fix ipv6cp-use-persistent option when remote address is specified (#246)
X-Git-Tag: ppp-2.5.0~89
X-Git-Url: https://git.ozlabs.org/?p=ppp.git;a=commitdiff_plain;h=6891c82b8987f08baa9a16a2a0ae93b511323ea5

ipv6cp: Fix ipv6cp-use-persistent option when remote address is specified (#246)

Option ipv6cp-use-persistent affects only local interface identifier (local
link-local address). It does not affects remote peer interface identifier
(and remote link-local address) therefore ipv6cp-use-persistent option
should not depend on remote address.
