PR#912 broken syncd/swss on Arista-7260CX3-64 platform #14

've tried images before and after PR #912. It appears that this PR broke sonic on Arista-7260CX3-64 platform. Not sure if any other Arista/Broadcom platform would encounter this same issue.

The issue seemingly related to syncd unable to discover the Broadcom device on PCI bus. Though lspci shows them:

Guohan believes that this issue was caused by Arista driver resets the PCI device after loading Broadcom driver.

This issue could be solved by restarting opennsl after boot up.
