ivshmem is a path to the guest using DPDK rings that was
introduced before userspace vhost was available in the OVS-DPDK
datapath. ivshmem is external to OVS but the scheme of using it
with DPDK rings is documented.
Remove ivshmem instruction documentation because:
- The ivshmem library has been removed in DPDK since DPDK 16.11.
- The instructions/scheme provided will not work with current
supported and future DPDK versions.
- The linked patch needed to enable support in QEMU has never
been upstreamed and does not apply to the last 4 QEMU releases.
- Userspace vhost has become the defacto OVS-DPDK path to the guest.
