From f6d8dc235553761a2541f7a6b782488160db03a7 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 7 Nov 2023 12:40:16 +1100 Subject: pif: Pass originating pif to tap handler functions For now, packets passed to the various *_tap_handler() functions always come from the single "tap" interface. We want to allow the possibility to broaden that in future. As preparation for that, have the code in tap.c pass the pif id of the originating interface to each of those handler functions.
