[Chassis]: Ports take too long to come up due to delayed port up notification processing by orchagent

[mannytaheri]

Issue Description

The ports take more the 20 minutes to come up due to the delayed port up notification processing by orchagent after reload/reboot in T2 topo.

Results you see

The port up notifications are queued due to lot of bgp route (34000 routes) updates and take a long time. This occurs after a config reload or a reboot.

Results you expected to see

The bgp routes update should be handled correctly and ports should come up in a reasonable time.

Is it platform specific

generic
