Open issues for 2.6

None critical / blocker for the release, but still

761: diskd unstable

1584: WCCPv2 unable to register with more than one router on Linux (IP
ID IOS issue)

1602: Need to implement TCP fallback for DNS

1638: Connection pinning a bit too agressive. Should not pin due to
local authentication, only forwarded authentication..
