On Scale testbed there are 2 main differences: 1. There are much more PTF ports(512) 2. There are much more OVS and interface configurations Those lead to: 1. NIC would take more time to handle the receiving packets 2. PTF could take more time to process As a result: 1. More time to spend in ptf function testutils.verify_packet, and with more timeouts, the function verify_packet would capture the packet.

This change ensures we successfully copy the pfc_gen_file on both EOS and SONiC fanout switches by first creating the
/mnt/flashdirectory (which, by default, doesn't exist on SONiC devices). It should be a no-op on EOS devices, where the/mnt/flashdirectory should already exist.
