Hi,
I'm testing ikev2 and there is something error in my test:
VPP# ikev2 initiate del-sa ee25d9aa4e7a0f1a
0: ikev2_generate_message:1774: sa state changed to
IKEV2_STATE_NOTIFY_AND_DELETE

'
The '(vnet_buffer (p0)->sw_if_index[VLIB_TX] ' is (u32) ~ 0 when 'del-sa'
execute success.
The '(vnet_buffer (p0)->sw_if_index[VLIB_TX] ' is 2 when 'del-sa' execute fail.
By the way, the fault doesn't happen every time.
What should I do to solve the problem?
Thanks,
xyxue
