Thanks for the patch.  Please see below for a few comments.
This patch needs a rebase too.

Instead of using shash_node as input parameter,  I'd suggest changing it to

setup_qos(const char *egress_iface,  const char *logical_port, struct
hmap *queue_map)

I don't understand the above logic.  The above for loop, loops through
all the ovs ports of br-int, every time
consider_vif_lport() is called.  And this seems inefficient to me.

consider_vif_lport() is called for each VIF/container/virutal port in
binding_run() (when a full recompute happens)
and when a port binding or an ovs interface change handler is called.

Instead of the above loop,  why can't this function just check if the
lbinding->iface->external_ids has "ovn-egress-iface"
set and if so add it to the b_ctx_out->egress_ifaces shash ?
