+Date: Wed, 10 Jan 2024 23:30:17 -0800
+Subject: [PATCH] Don't look up the ifindex for fallback
+
+If sending a packet on the "fallback" interface, then don't try to get the
+ifindex for that interface. There will never be an actual interface named
+"fallback" in SONiC (at least, not one that we will want to use).
+
+This might save 0.009-0.012 seconds per upstream server, and when there
+are as many as 48 upstream servers, it can save about 0.4-0.5 seconds of
+time. This then allows dhcrelay to process more packets.
