I understand that,

*"""*

*Open vSwitch 2.4 and later by default hashes the source and
**destination Ethernet address, VLAN ID, Ethernet type, IPv4/v6
**source and destination address and protocol, and for TCP and SCTP
**only, the source and destination ports.  The hash is "symmetric",
**meaning that exchanging source and destination addresses does not
**change the bucket selection.*

*"""*

*How does bucket size impact selection ? If entries are added/deleted
to/from bucket, then for the same 5tuple is it rehashed and new entry
could get selected ?*


Thanks,

Ahmed
