Currently, whenever isc-dhcp-relay forwards a packet upstream,
internally, it will try to send it on a "fallback" interface. My
understanding is that this isn't meant to be a real interface, but
instead is basically saying to use Linux's regular routing stack to
route the packet appropriately (rather than having isc-dhcp-relay
specify specifically which interface to use).
The problem is that on systems with a weak CPU, a large number of
interfaces, and many upstream servers specified, this can introduce a
noticeable delay in packets getting sent. The delay comes from trying to
get the ifindex of the fallback interface. In one test case, it got to
the point that only 2 packets could be processed per second. Because of
this, dhcrelay will easily get backlogged and likely get to a point
where packets get dropped in the kernel.
Fix this by adding a check saying if we're using the fallback interface,
then don't try to get the ifindex of this interface. We're never going
to have an interface named this in SONiC.
