[PATCH net-next 00/13] net: Various VRF patches

[David Ahern <dsa@cumulusnetworks.com>]

Various fixes and features for VRF over the past few months.

Patch 1 creates the FIB tables when VRF device is created.

Patch 2 is a prep for 3 which allow sends via cmsg/IP-PKTINFO on interfaces
enslaved to a VRF device.

Patch 4 fixes missing TCP reset / ECONNREFUSED packets in response to
packets to unused ports.

Patch 5 moves the packet hook to L3. It simplifies the overhead of VRFs,
removing a lot of packet path code from VRF driver and is the foundation
for the patches after it.

Patch 6 fixes IP{6}_PKTINFO to returned the index of the enslaved
interface rather than the VRF device. A required feature for proper
VRF support.

Patches 7 and 8 provide support for locally originated traffic to local
addresses.

Patch 9 accommdates a change to the IP6 route lookups - passing flags
to l3mdev/vrf route lookups.

Patch 10 provides support for IPv6 multicast and link local addresses.

Patch 11 protects access to the cached vrf dst entries which can be
deleted on 1 cpu while processing packets on another cpu.

Patches 12 and 13 fix up IPv6 source address selections.
