Subject: tcp: set sw_if_index in tcp src-address cli
X-Git-Tag: v22.06-rc0~92
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=89618da2f719cc6b566a7e8f428f12917aeaaea5;p=vpp.git

tcp: set sw_if_index in tcp src-address cli

the receive dpo added by tcp src-address cli do not have a valid sw_if_index ,
ip4_local_check_src() and tcp_input_lookup_buffer() will set ~0 to vnet_buffer(b)->sw_if_index[VLIB_RX],
which will cause crash in tcp46_reset_inline,

Type: fix
