Commit: 6f202d8 (dpdk_merge_2_9)
Author: Ian Stokes
Message: netdev-dpdk: Reintroduce shared mempools.
This commit manually reverts the current per port mempool model to the
previous shared mempool model for DPDK ports.
OVS previously used a shared mempool model for ports with the same MTU
configuration. This was replaced by a per port mempool model to address
issues flagged by users such as:
However the per port model has a number of issues including:
1. Requires an increase in memory resource requirements to support the same
number of ports as the shared port model.
2. Incorrect algorithm for mbuf provisioning for each mempool.
These are considered blocking factors for current deployments of OVS when
upgrading to OVS 2.9 as a user may have to redimension memory for the same
deployment configuration. This may not be possible for users.
For clarity, the commits whose changes are removed include the
netdev-dpdk: Create separate memory pool for each port: d555d9b
netdev-dpdk: fix management of pre-existing mempools: b6b26021d

netdev-dpdk: Remove unused MAX_NB_MBUF: bc57ed9
netdev-dpdk: Fix mempool creation with large MTU: af5b0da
Due to the number of commits and period of time they were introduced
over, a simple revert was not possible. All code from the commits above
is removed and the shared mempool code reintroduced as it was before its
Code introduced by commit

has been modified to work with the shared mempool model.
