Before flushing offloads of a removed port was supported by [1], it was
necessary to flush the 'marks'. In doing so, all offloads of the PMD are
removed, include the ones that are not related to the removed port and
that are not modified following this removal. As a result such flows are
evicted from being offloaded, and won't resume offloading.
As PMD offload flush is not necessary, avoid it.
