…c-net#19003) * [crm] Fix test failures on SN4700 by batching neighbor creation test_crm_nexthop_group was failing on sn4700 testbeds due to a known orchagent crash. The crash is caused by a few factors: - Expected neighbor entry missing from kernel, causing tunnel-route to be programmed for unresolved nexthop. - tunnel-route being removed when nexthop group was deleted - route bulker ending early due to ITEM_NOT_FOUND (not processing remaining bulk removes) - next-hop group delete failing due to OBJECT_IN_USE. This PR addresses the first issue. During neighbor generation for the test, some of the neighbor updates were being missed from APPL_DB on sn4700 devices. Previously, the neighbors were programmed in the kernel in a single ip command, this fix splits up the neighbor programming into batches in order to prevent updates from being dropped.

This PR addresses the first issue.

Previously, the neighbors were programmed in the kernel in a single ip command, this fix splits up the neighbor programming into batches in order to prevent updates from being dropped.
Summary:

Type of change
Back port request
Approach
What is the motivation for this PR?
CRM test was failing on dualtor sn4700 platforms
How did you do it?
buffered neighbor creation to prevent updates from being dropped
How did you verify/test it?
ran test case on sn4700 dualto testbed
Any platform specific information?
only changes test run on sn4700
