ip ipsec: Remove IPSec SPI-0 punt reason
Type: fix There's no call for an SPI-0 punt reason with UDP encap, since it's only with UDP encap that the ambiguity between IKE or IPSEC occurs (and SPI=0 determines IKE). Enhance the punt API to dum ponly the reason requested, so a client can use this as a get-ID API Change-Id: I5c6d72b03885e88c489117677e72f1ef5da90dfc Signed-off-by: Neale Ranns <nranns@cisco.com>
