ip: Add ip46-local node for local swif[rx]
Type: improvement
This adds a new ip[46]-receive node, sibling
of ip[46]-local. Its goal is to set
vnet_buffer (b)->ip.rx_sw_if_index to the
sw_if_index of the local interface.
In dependant nodes further down the line (e.g.
hoststack) we then set sw_if_idx[rx] to this
value. So that we know which local interface
did receive the packet.
The TCP issue this fixes is that :
On accepts, we were setting tc->sw_if_index
to the source sw_if_index. We should use
the dest sw_if_index, so that packets
coming back on this connection have the
right source sw_if_index. And also setting
it in the tx-ed packet.
