Standard P4 does not have any means for the data plane to change tables.
However, various architectures can provide extensions to enable this behavior if the hardware supports it.

In the v1model counters and registers are closest to what you want.

Subject: [P4-dev] Manipulating Table Entries in P4 program.

Hello Everyone,
Although performing CRUD operations on the table entries is the responsibility of control plane, Still curious about if it is possible to do it in data plane in our P4 program as well.
For example, If I need to remove an entry from the table on receiving a specific flag in packet.

Kamal Bhatt.
