The FastL4 profile option pva-offload-state was deprecated in v14.1.0: https://cdn.f5.com/product/bugtracker/ID705311.html On upgrade from BIG-IP version 14.0.0 or earlier to version 14.1.0 or later, the pva-offload-state is not migrated properly to the new FastL4 options, if set to a non-default value. The new FastL4 profile options are tcp-pva-whento-offload and other-pva-whento-offload.
Hardware-accelerated flows (ePVA) are accelerated based on the new default values instead of the non-default value configured prior to upgrade. This can cause flows to be accelerated based on different constraints. In the case where the pva-offload-state was set to established (EST), it can cause flows to offload prematurely.
A non-default setting of pva-offload-state in the FastL4 profile.
Set the new FastL4 profile options to values that are equivalent to the non-default pva-offload-state setting. If pva-offload-state is set to establish (EST), then the following should be set for equivalent flow offloading behavior: tcp-pva-whento-offload = establish other-pva-whento-offload = after-packets-both-direction
